Iyini i-methyl tin stabilizer?

I-methyl tinama-stabilizers awuhlobo lwenhlanganisela ye-organotin evame ukusetshenziswa njengeziqinisi ukushisa lapho kukhiqizwa i-polyvinyl chloride (PVC) namanye ama-polymers e-vinyl. Lezi zinzisi zisiza ukuvimbela noma ukunciphisa ukuwohloka kokushisa kwe-PVC phakathi nokucubungula nokusebenzisa, ngaleyo ndlela kuthuthukise ukuqina nokusebenza kwento. Nawa amaphuzu abalulekile mayelana nezinzinzi ze-methyl tin:

Isakhiwo Sekhemikhali:I-Methyl tin stabilizers yizinhlanganisela ze-organotin eziqukethe amaqembu e-methyl (-CH3). Izibonelo zifaka i-methyl tin mercaptides kanye ne-methyl tin carboxylates.

I-Stabilizing Mechanism:Lezi zinzisi zisebenza ngokusebenzisana nama-athomu e-chlorine akhishwe ngesikhathi sokuwohloka kokushisa kwe-PVC. Ama-methyl tin stabilizer anciphisa lawa ma-radicals e-chlorine, awavimbe ekuqaliseni okunye ukusabela kokuwohloka.

Izicelo:I-Methyl tin stabilizers isetshenziswa kabanzi ezinhlelweni ezahlukahlukene ze-PVC, kufaka phakathi amapayipi, okokufakwayo, amaphrofayili, izintambo, namafilimu. Zisebenza kahle kakhulu ezimeni zokucubungula izinga lokushisa eliphezulu, njengalezo okuhlangatshezwane nazo ngesikhathi sokukhipha noma sokubumba umjovo.

Izinzuzo:

Ukuzinza Okushisayo Okuphezulu:Ama-Methyl tin stabilizer ahlinzeka ngokuzinza okushisayo okusebenzayo, okuvumela i-PVC ukuthi imelane namazinga okushisa aphakeme ngesikhathi sokucubungula.

Ukugcina Umbala Okuhle:Banikela ekugcineni ukusimama kombala wemikhiqizo ye-PVC ngokunciphisa ukuguga okubangelwa ukuwohloka kokushisa.

Ukumelana Nokushisa Okuhle Kakhulu:I-Methyl tin stabilizers isiza imikhiqizo ye-PVC ukumelana nokuwohloka ngokuhamba kwesikhathi lapho ichayeke ekushiseni nasezimeni zemvelo.

Ukucatshangelwa Kokulawula:Nakuba kuphumelela, ukusetshenziswa kwezinhlanganisela ze-organotin, okuhlanganisa i-methyl tin stabilizers, kuye kwabhekana nokuhlolwa okulawulwayo ngenxa yokukhathazeka kwemvelo nempilo ehambisana nezinhlanganisela zethini. Kwezinye izifunda, imikhawulo yokulawula noma ukuvinjelwa kuye kwabekwa kwezinye iziqinisi ze-organotin.

Ezinye izindlela:Ngenxa yezinguquko zokulawula, imboni ye-PVC ihlole ezinye izinzisi zokushisa ezinomthelela oncishisiwe wemvelo. Iziqinisi ezisekelwe ku-calcium nezinye izindlela ezingezona amathini ziya ngokuya zisetshenziswa ekuphenduleni imithetho eguquguqukayo.

Kubalulekile ukuqaphela ukuthi izimfuneko zokulawula zingahluka ngokwesifunda, futhi abasebenzisi kufanele bahambisane nemithetho kanye nemihlahlandlela yendawo lapho bekhetha futhi besebenzisa iziqinisi ze-PVC. Hlala uthintana nabahlinzeki, imihlahlandlela yemboni, neziphathimandla ezifanele zokulawula ukuze uthole ulwazi lwakamuva mayelana nezinketho zokuzinzisa nokuhambisana.
