Yintoni na into PVC

I-PVC yi-polyvinyl chloride, eyipolymer eyenziwe nge-vinyl chloride monomer phantsi kwesenzo se-peroxide, i-azo compounds kunye nabanye abaqalisi, okanye phantsi kwesenzo sokukhanya kunye nobushushu ngokwendlela ye-polymerization yamahhala.I-PVC yenye yezona zixhobo zeplastiki ezinkulu zehlabathi, ezisetyenziswa ngokubanzi kumashishini ahlukeneyo.

Yintoni iPVC?I-PVC yinto eqhelekileyo ebomini.Loluphi uhlobo lwemathiriyeli yePVC?Makhe sijonge namhlanje.[umbono wePVC] PVC yipolyvinyl chloride eneneni, eyipolymer eyenziwe ngevinyl chloride monomer eneperoxide, i-azo compound kunye nabanye abaqalisi, okanye phantsi kwesenzo sokukhanya kunye nobushushu ngokwendlela yokwenziwa kwepolymerization yasimahla. .

[Iimpawu zePVC]: I-PVC ngumgubo omhlophe kunye nesakhiwo se-amorphous, kunye nobushushu beglasi yokutshintsha yi-77 ~ 90 ℃.Ukutshintsha kweglasi yingcamango entsonkothileyo.Kwi-PVC powder, i-glass transition kukuba ngaphakathi kolu luhlu lobushushu, i-PVC iya kutshintsha ukusuka kumgubo omhlophe ukuya kwimeko yeglasi.I-PVC yeglasi iyakuqala ukubola malunga ne-170 ℃.Uzinzo olubi kukukhanya kunye nobushushu, kulula ukubola kunye nokuvelisa i-hydrogen chloride.
[ukwenzakala kwePVC].Ukusuka kwiimpawu zePVC, sinokubona ukuba iPVC ayinakusetyenziswa yodwa.Kwizicelo ezisebenzayo, i-stabilizers kufuneka yongezwe ukuphucula ukuzinza kubushushu nokukhanya.Kufuneka sinikele ingqalelo ekhethekileyo apha.Kwi-2017, uluhlu lwe-carcinogens olupapashwe yi-arhente yamazwe ngamazwe yophando ngomhlaza we-World Health Organization yahlelwa kwangaphambili ukuba ibhekiselele, kwaye i-PVC ifakwe kuluhlu lweentlobo ezintathu ze-carcinogens.Ngoko ke, kubomi bemihla ngemihla, zama ukungasebenzisi izitya zePVC ukubamba ukutya, singasathethi ke ngamanzi ashushu.

[usetyenziso lwePVC], njengenye yeeplastiki ezinkulu zehlabathi, iPVC isetyenziswa ngokubanzi kwizinto zokwakha, iimveliso zoshishino, iimfuno zemihla ngemihla, isikhumba somgangatho, iithayile zomgangatho, isikhumba sokwenziwa, imibhobho, iingcingo kunye neentambo, iifilimu zokupakisha, iibhotile. , izinto zogwebu, izinto zokutywina, ubungakanani befiber, njl.
