Isinyithi se-methyli-stabilizers luhlobo lwekhompawundi ye-organotin edla ngokusetyenziswa njengezinzisi zobushushu ekuveliseni i-polyvinyl chloride (PVC) kunye nezinye iipholima zevinyl. Ezi zizinzi zinceda ukuthintela okanye ukunciphisa ukuthotywa kwe-thermal ye-PVC ngexesha lokucubungula kunye nokusetyenziswa, ngaloo ndlela kuphucula ukuqina kunye nokusebenza kwezinto. Nanga amanqaku aphambili malunga nezinzinzi ze-methyl tin:
Ulwakhiwo lweMichiza:I-Methyl tin stabilizers yi-organotin compounds equkethe amaqela e-methyl (-CH3). Imizekelo ibandakanya i-methyl tin mercaptides kunye ne-methyl tin carboxylates.
Uzinziso lweNkqubo:Ezi zizinzi zisebenza ngokusebenzisana neeathom zeklorine ezikhutshwe ngexesha lokuthotywa kwe-PVC yobushushu. Izizinzi ze-methyl tin zinciphisa ezi radicals zeklorini, zibathintele ekuqaliseni ukusabela kokuthotywa komgangatho.
Usetyenziso:I-Methyl tin stabilizers isetyenziswa ngokubanzi kwizicelo ezahlukeneyo zePVC, kubandakanya imibhobho, izifakelo, iiprofayili, iintambo, kunye neefilim. Zisebenza ngokukodwa kwiimeko eziphezulu zokushisa, ezifana nezo zidibene ngexesha lokukhupha okanye ukubunjwa kwenaliti.
Izibonelelo:
Uzinzo oluPhezulu lweThermal:I-Methyl tin stabilizers ibonelela ngokuzinza okusebenzayo kwe-thermal, evumela i-PVC ukuba imelane namaqondo okushisa aphezulu ngexesha lokucubungula.
UkuGcina Umbala oLungileyo:Bafaka isandla ekugcineni ukuzinza kombala weemveliso zePVC ngokunciphisa ukuguquka kwebala okubangelwa ukuthotywa kwe-thermal.
Okugqwesileyo kokumelana nokuguga kobushushu:I-Methyl tin stabilizers inceda iimveliso ze-PVC zixhathise ukuthotywa kwexesha xa zibonakaliswe kubushushu kunye neemeko zokusingqongileyo.
Iingqwalasela zoLawulo:Nangona kusebenza, ukusetyenziswa kwe-organotin compounds, kuquka i-methyl tin stabilizers, ijongene nokuhlolwa kokulawula ngenxa yokukhathazeka kokusingqongileyo kunye nempilo ehambelana ne-tin compounds. Kweminye imimandla, izithintelo zokulawula okanye ukuvinjelwa kuye kwanyanzeliswa kwi-organotin stabilizers ethile.
Ezizezinye:Ngenxa yeenguqu ezilawulayo, imboni yePVC iye yahlola ezinye izinzisi zobushushu ezinefuthe elincitshisiweyo lokusingqongileyo. I-calcium-based stabilizers kunye nezinye iindlela ezingezona-tin zisetyenziswa kakhulu ekuphenduleni imimiselo eguqukayo.
Kubalulekile ukuqaphela ukuba iimfuno zolawulo zinokwahluka ngokwemimandla, kwaye abasebenzisi kufuneka babambelele kwimimiselo yasekhaya kunye nezikhokelo xa bekhetha kwaye besebenzisa izinzisi zePVC. Soloko ubonisana nababoneleli, izikhokelo zeshishini, kunye nabasemagunyeni abafanelekileyo bolawulo malunga nolwazi lwamva nje malunga nokhetho lokuzinzisa kunye nokuthotyelwa.
