Ziziphi iziZinzisi zeNkokeli? Yintoni ukusetyenziswa kwelothe kwiPVC?

Izinzisi zokukhokela, njengoko igama libonisa, luhlobo lwe-stabilizer olusetyenziselwa ukuveliswa kwe-polyvinyl chloride (PVC) kunye nezinye iipolymers ze-vinyl. Ezi zinzisi ziqulethe i-lead compounds kwaye zongezwa kwiifom ze-PVC ukukhusela okanye ukunciphisa ukuchithwa kwe-thermal ye-polymer ngexesha lokucubungula kunye nokusetyenziswa.Isikhokelo sokuzinzisa kwiPVCziye zasetyenziswa ngokubanzi kwishishini lePVC, kodwa ukusetyenziswa kwazo kwehlile kwezinye iingingqi ngenxa yeenkxalabo zokusingqongileyo kunye nempilo ehambelana nelothe.

Amanqaku aphambili malungaizinzisi ezikhokelayoziquka:

 

Uzinziso lweNkqubo:

I-Lead stabilizers isebenza ngokuthintela ukuthotywa kwe-thermal ye-PVC. Banciphisa i-acidic byproducts eyenziwe ngexesha lokuqhekeka kwe-PVC kumaqondo obushushu aphakamileyo, ukuthintela ukulahleka kwesakhiwo se-polymer ingqibelelo.

 

Usetyenziso:

I-lead stabilizers isetyenziswe ngokwesiko kwiintlobo ngeentlobo zezicelo ze-PVC, kubandakanywa imibhobho, ukugquma intambo, iiprofayili, amaphepha, kunye nezinye izinto zokwakha.

 

Uzinzo Lobushushu:

Babonelela ngokuzinzisa ubushushu obusebenzayo, ukuvumela i-PVC ukuba iqhutywe kumaqondo aphezulu ngaphandle kokuthotywa okukhulu.

 

Ukuhambelana:

I-Lead stabilizers ziyaziwa ngokuhambelana kwazo kunye ne-PVC kunye nokukwazi kwabo ukugcina iimpawu zoomatshini kunye nezomzimba zepolymer.

 

Ukugcina Umbala:

Bafaka isandla ekuzinzeni kombala weemveliso zePVC, kunceda ukuthintela ukuguquka kwebala okubangelwa ukuthotywa kwe-thermal.

 

Iingqwalasela zoLawulo:

Ukusetyenziswa kwezizinzisi zelothe kuye kwajongana nezithintelo ezandayo zolawulo ngenxa yeenkxalabo zokusingqongileyo kunye nempilo enxulumene nokuvezwa kwelothe. Ilothe sisiyobisi esiyityhefu, yaye ukusetyenziswa kwayo kwiimveliso zabathengi nakwizinto zokwakha kuye kwalinganiselwa okanye kwavalwa kwimimandla eyahlukahlukeneyo.

 

Ukutshintshela kwezinye iindlela:

 

Ukuphendula kwimimiselo yokusingqongileyo kunye nempilo, imboni ye-PVC iye yatshintshela kwiindlela zokuzinzisa kunye nefuthe eliphantsi lokusingqongileyo. I-calcium-based stabilizers, i-organotin stabilizers, kunye nezinye iindlela ezingezizo ezikhokelayo zisetyenziswa kakhulu kwi-PVC formulations.

 

Impembelelo yokusingqongileyo:

Ukusetyenziswa kwezizinzisi zelothe kuye kwaphakamisa inkxalabo malunga nokungcoliseka kwendalo kunye nokuvezwa kwelothe okunokubakho. Ngenxa yoko, iinzame zenziwe zokunciphisa ukuthembela kwizinzisi zelothe ukunciphisa impembelelo yazo yokusingqongileyo.

 

Kubalulekile ukuqaphela ukuba uguquko olusuka kwizizinzisi zelothe lubonisa umkhwa obanzi obhekiselele kubume bendalo kunye nezenzo zokukhathalela impilo kwishishini lePVC. Abavelisi kunye nabasebenzisi bayakhuthazwa ukuba bathathe ezinye iindlela ezihlangabezana neemfuno zolawulo kunye negalelo kuzinzo. Hlala unolwazi malunga nemigaqo yamva nje kunye nezenzo zeshishini malunga nokusetyenziswa kozinziso.
