In general, MSDS is used to determine whether the goods are suitable for sea transportation and what appropriate mode of transportation is used to ensure transportation safety. When booking a specific cargo for export, the carrier (shipping company) will require an MSDS, and all personnel who come into contact with or may come into contact with the cargo (including loading and unloading personnel, depot/warehouse personnel, etc.) will need an MSDS. Operators must follow the guidelines and instructions of MSDS for correct operation and disposal, especially in emergencies such as package damage and leakage, it is difficult to understand the situation without MSDS, which will delay rescue, and blind action will lead to serious consequences.

The 16 contents of the MSDS issued by authoritative institutions are very accurate, for example, the Shanghai Institute of Chemical Industry can issue them. But now basically the manufacturer compiles the MSDS by itself, and the accuracy is not high, so many times it is necessary to refer to the identification certificate to judge whether it is ordinary goods or dangerous goods. In the actual trade and transportation of chemical products, the accuracy of MSDS is extremely critical. It is very common for manufacturers to compile their own MSDS inaccurately, which makes there are many hidden dangers when judging the nature of the goods. Since an inaccurate MSDS may not accurately reflect the characteristics of chemicals, it may lead to misjudgment as to whether the goods are suitable for sea transportation and what mode of transportation to use.

When booking cargo, if the carrier is acting on an inaccurate MSDS, it may transport the cargo that should have been handled in accordance with the requirements for the transport of dangerous goods as general cargo, or vice versa. Not only can this be a violation of transport regulations, but it also poses a significant risk to transport safety. For example, if an accident occurs during transportation, an inaccurate MSDS cannot provide accurate information to rescuers, such as when a chemical is leaked, it is difficult for rescuers to take effective response measures if it is not clear about its hazard category and suitable fire extinguishing medium.

Inaccurate MSDS can also prevent operators from operating correctly during handling, disposal, and storage. For example, for some chemicals that require special storage conditions, if the MSDS does not accurately state, it may lead to improper storage, which can lead to chemical reactions and safety accidents. When it comes to exposure control and personal protection, the wrong MSDS can lead workers to use inappropriate protective gear that prevents them from effectively protecting themselves from chemical hazards.

For the measure of judging whether ordinary goods or dangerous goods are made by referring to the appraisal certificate, although it can make up for the inaccuracy of the manufacturer's self-compiled MSDS to a certain extent, there are also some limitations. On the one hand, obtaining an appraisal certificate can require additional time and cost; On the other hand, there may be differences in standards and testing methods between different accreditation bodies, which may also lead to inconsistencies in judgment results.

To sum up, MSDS plays an indispensable role in the production, transportation, storage and emergency treatment of chemical products, but the current situation of inaccurate MSDS compiled by manufacturers has seriously affected its function, and measures need to be taken to improve the accuracy of MSDS to ensure the safety and orderly conduct of related activities in the chemical industry.

In the actual trade and transportation of chemical products, the accuracy of the MSDS is crucial. It is not uncommon for manufacturers to compile their own MSDS inaccurately, which makes there are many hidden dangers when judging the nature of goods. Since an inaccurate MSDS may not accurately reflect the characteristics of chemicals, it may lead to misjudgment as to whether the goods are suitable for sea transportation and what mode of transportation to use.

When booking cargo, if the carrier relies on an inaccurate MSDS, it may transport the cargo as general cargo that should have been handled in accordance with the requirements for the transport of dangerous goods, or vice versa. Not only can this be a violation of transport regulations, but it also poses a significant risk to transport safety. For example, if an accident occurs during transportation, an inaccurate MSDS cannot provide accurate information to rescuers, such as when a chemical is leaked, it is difficult for rescuers to take effective countermeasures if it is not clear about its hazard category and suitable fire extinguishing medium.

In the handling and storage process, inaccurate MSDS can also prevent operators from operating correctly. For example, for some chemicals that require special storage conditions, if the MSDS is not accurately stated, it may lead to improper storage, which can lead to chemical reactions and safety accidents. When it comes to exposure control and personal protection, the wrong MSDS can lead workers to use inappropriate protective equipment that prevents them from effectively protecting themselves from chemical hazards.

For the measure of judging whether general goods or dangerous goods are based on the appraisal certificate, although it can make up for the inaccuracy of the manufacturer's self-compiled MSDS to a certain extent, there are also some limitations. On the one hand, the acquisition of an appraisal report may require additional time and cost; On the other hand, there may be differences in standards and testing methods between different accreditation bodies, which may also lead to inconsistencies in judgment results.

{\fnCandara\fs60\b1\4cH000000\4aH80}Teman-teman yang terlibat dalam proses SMT SMD seharusnya tidak ada orang asing untuk melekat. Saat membelipasta solder, mereka sering diminta untuk memilih tipe dengan hati-hati menurut kebutuhan sebenarnya dan menguji sampel dengan pembuat tentara Nofel. Ini adalah bahan yang sangat penting. Jadi, peran apa yang begitu penting? Suzhou Neufeld berikutnya untuk interpretasi Anda:

Pada tahun 1970-an, teknologi pegunungan permukaan baru saja mulai meningkat, juga dikenal sebagai SMT. Ini adalah pads papan sirkuit dicetak yang dicetak dan dikelilingi dengan teknologi pasta solder, dalam pads paste solder yang dikelilingi tepat melekat permukaan komponen elektronik, dan menurut profil suhu reflow spesifik untuk memanaskan papan sirkuit, sehingga pasta solder meleleh. Setelah komposisi legasinya dingin dan dikonsolidasi, sebuah kongsi solder terbentuk antara komponen dan papan sirkuit cetak untuk mencapai koneksi komponen elektronik soldered.

Pasta prajurit adalah jenis baru bahan prajurit yang muncul bersama dengan muncul teknologi SMT. Ini adalah semacam solder yang digunakan untuk menghubungkan elektroda bagian-bagian dengan pad papan sirkuit, dan terutama digunakan dalam industri SMT untuk soldering komponen elektronik seperti kondensator, resistor dan ICs di permukaan PCB. Pasta prajurit pada suhu kamar juga memiliki tingkat tertentu viskositas, dapat sementara menempel komponen elektronik di posisi yang ditetapkan tetap, dalam suhu penywelding, dengan solven dan bagian dari volatilisasi aditif, pasta prajurit terlebih dahulu meleleh untuk memperbaiki pins dan soldering, untuk mendinginkan setelah komponen elektronik dan pads sirkuit cetak penywelded bersama-sama untuk membentuk koneksi stabil.

Pasta Solderadalah sistem kompleks, adalah campuran bubuk solder, aliran dan aditif logam lainnya ke dalam pasta, dan mengubah komposisinya untuk memenuhi kebutuhan solder dari produk yang berbeda. Oleh karena itu, komponen yang membuat pasta tentara semua memiliki peran yang berbeda.

Peran pasta solder terutama dibagi ke modul-modul ini, yang pertama adalah peran serbuk liga, adalah menyelesaikan koneksi mekanik dan listrik antara komponen elektronik dan papan sirkuit.

Kedua, ada aliran: itu adalah substansi partikel bubuk tin, yang menyediakan reulogi dan kemudahan yang tepat, memudahkan pemindahan panas ke area perang, mengurangi ketegangan permukaan tentara, dan mencegah re-oksidasi tentara dan permukaan perang selama perang. diantara mereka, peran komponen berbeda adalah seperti ini:

1, solven (Solvent): Komponen adalah solven komponen solder, dalam proses campuran pasta solder bermain peran dalam mengatur keseluruhan hidup pasta solder memiliki dampak tertentu;

2, resin (Resins): komponen terutama memainkan peningkatan pada pegangan pasta solder, tetapi juga untuk melindungi dan mencegah peran oksidasi PCB solder lagi setelah penywelding; komponen ini bermain peran yang sangat penting dalam bagian yang tetap.

3, aktivator (Aktivasi): Komponen ini terutama bermain peran untuk menghapus lapisan permukaan pad film tembaga PCB dan bagian oksidasi bagian-bagian yang ditelan, dan pada saat yang sama memiliki efek untuk mengurangi ketegangan permukaan tin, lead;

4, agen thixotropic (Thixotropic): komponen adalah terutama untuk mengatur viskositas pasta solder dan prestasi cetakan, untuk bermain peran dalam cetakan untuk mencegah fenomena menarik ekor, adhesi dan sebagainya;

Beberapa jenis spesial pasta solder cenderung untuk kering keluar, dan pemasok paste solder umum dipersediakan dengan solven spesial - lebih tipis. Namun, untuk beberapa merk pasta solder, tidak ada masalah kualitas besar sendiri, sehingga mereka tidak dapat menyediakan penyelesaian untuk Anda menambahkan. Langkah berikutnya adalah untuk Suzhou Noble Flower prajurit memasang pasta untuk mengatakan beberapa kata:

Ketika pasta solder kering, jangan pernah dilusi dengan air.

Pasta tinya benar-benar dilarang untuk mencampur dengan air, jika sejumlah kecil pasta tinya untuk digunakan kadang-kadang, dapat dicampur dengan sejumlah kecil alkohol, bergetar dengan baik setelah digunakan; jika isi pasta tin besar, harus dicampur dengan penapis khusus.

Pasta peneliti dalam penyimpanan dan penggunaan proses akan selalu menghasilkan reaksi kimia, meskipun reaksi ini tidak dapat dihindari, tetapi paste peneliti yang cukup dirancang dalam penggunaan normal kondisi tingkat reaksi seharusnya cukup lambat, sehingga hidup layanannya cukup untuk menghadapi kebutuhan produksi normal. Ini dapat dipindahkan dalam truk pendingin dan disimpan di gudang pabrik menggunakan beku untuk pendinginan. Pasta Solder yang susah untuk kering sering adalah hasil dari cacat dalam desain formulasi. Selain itu, memastikan lingkungan operasi yang sesuai dan pengurusan standar dapat memperpanjang hidup paste. Faktor lain, seperti evaporasi solven selama penggunaan, juga mungkin memiliki efek pada kehidupan layanan, tetapi bukan faktor utama.

Dalam penggunaan pasta solder dalam proses, untuk menjaga spesifikasi untuk menggunakan pasta solder, jika tidak akan mempengaruhi karakteristik pasta solder sendiri, yang berasal dari prajurit yang buruk; bahwa untuk menggunakan merk paste prajurit yang lebih baik.

Direkomansikan Noble Flower pasta prajurit bebas plum, jangkauan luas penggunaan, prajurit perlindungan lingkungan paste profesional untuk istirahat yakin bahwa dapat memenuhi produksi SMT resistensi suhu memiliki keperluan penywelding khusus produk. Konsultasi staf layanan pelanggan, untuk Anda untuk merekomendasikan kualitas tinggi, harga yang baik dan produk paste prajurit murah, kualitas yang baik dan layanan yang baik adalah keuntungan kami!
