I-YIHOO PVC (i-polyvinyl chloride) i-polymerization nezithasiselo zokuguqulwa
I-Polyvinyl chloride (i-PVC) iyi-polymer ye-vinyl chloride monomer (VCM) eyenziwe ipholishwa yi-peroxide, ama-compounds azo nezinye iziqalisi noma ngenqubo yokuphendula ye-radical yamahhala ngaphansi kokukhanya nokushisa. IVinyl chloride homo polymer ne-vinyl chloride co polymer ibizwa nge-vinyl chloride resin.
IPvv ibikade iyipulasitiki enkulu kunazo zonke emhlabeni futhi isetshenziswa kabanzi. Isetshenziswa kabanzi ezintweni zokwakha, imikhiqizo yezimboni, izidingo zansuku zonke, isikhumba saphansi, izitini phansi, isikhumba sokufakelwa, amapayipi, izintambo nezintambo, ifilimu yokupakisha, amabhodlela, izinto ezinegwebu, izinto zokuvala uphawu, imicu nokunye.

Izithasiselo ze-YIHOO PC (Polycarbonate)
IPolycarbonate (PC) iyi-polymer equkethe iqembu le-carbonate kuchungechunge lwamangqamuzana. Ngokuya ngesakhiwo seqembu le-ester, lingahlukaniswa nge-aliphatic, iphunga, i-aliphatic - enamakha nezinye izinhlobo. Izici eziphansi zemishini ye-aliphatic ne-aliphatic enamakha i-polycarbonate ikhawulela ukusetshenziswa kwazo kuma-plastiki wobunjiniyela. Kukhiqizwe kuphela okwezimboni kuphela i-polycarbonate enamakha. Ngenxa yobuningi besakhiwo se-polycarbonate, i-PC sekuyiplastiki ejwayelekile yobunjiniyela enezinga lokukhula okusheshayo phakathi kwamaplastikhi amahlanu wobunjiniyela.
I-PC ayimelani nokukhanya kwe-ultraviolet, i-alkali eqinile, nokuklwebheka. Iba phuzi ngokuchayeka isikhathi eside kwi-ultraviolet. Ngakho-ke, isidingo sezithasiselo eziguquliwe sibalulekile.

Izithasiselo ze-YIHOO TPU elastomer (Thermoplastic polyurethane elastomer)
I-Thermoplastic polyurethane elastomer (TPU), enezinto zayo ezinhle kakhulu nokusetshenziswa kwayo okubanzi, isibe ngesinye sezinto ezibalulekile ze-thermoplastic elastomer, ezinama-molecule aso ahambisana kakhulu nokuxhumeka okuncane noma okungenawo nhlobo amakhemikhali.
Kunama-crosslinks amaningi asemzimbeni akhiwe yizibopho ze-hydrogen phakathi kwamaketanga alinganayo e-polyurethane, adlala indima yokuqinisa ku-morphology yawo, ngaleyo ndlela anikeze izindawo eziningi ezinhle kakhulu, njenge-modulus ephezulu, amandla aphezulu, ukumelana okuhle kakhulu kokugqoka, ukumelana kwamakhemikhali, ukumelana ne-hydrolysis, okuphezulu futhi ongaphakeme lokushisa ukumelana futhi isikhunta ukumelana. Lezi zakhiwo ezinhle kakhulu zenza i-thermoplastic polyurethane isetshenziswe kabanzi emikhakheni eminingi njengezicathulo, ikhebula, okokugqoka, imoto, ezempilo nezempilo, ipayipi, ifilimu neshidi.

YIHOO okuphansi VOC yezimoto ngombala izithasiselo
Eminyakeni yamuva nje, ngokuqaliswa kwemithethonqubo yekhwalithi yomoya esemotweni, ikhwalithi yokulawulwa kwezimoto nele-VOC (ezinokuguquguquka kwe-Organic Compounds) sekube yingxenye ebalulekile yokuhlolwa kwekhwalithi yezimoto. I-VOC ingumyalo wama-organic compounds, ikakhulukazi ibhekisa ezingxenyeni zezimoto nezimpahla zemithwalo noma izinto zokwenziwa kwamakhemikhali, ikakhulukazi kufaka uchungechunge lwe-benzene, i-aldehydes namaketoni kanye ne-undecane, i-butyl acetate, i-phthalates nokunye.
Lapho ukuminyana kwe-VOC emotweni kufinyelela ezingeni elithile, kuzodala izimpawu ezinjengekhanda, isicanucanu, ukugabha nokukhathala, futhi kubangele nokudlikizela nekhoma ezimweni ezimbi kakhulu. Izolimaza isibindi, izinso, ubuchopho kanye nohlelo lwezinzwa, okuholele ekulahlekelweni inkumbulo neminye imiphumela emibi, okuyingozi empilweni yabantu.
