Hei ikoko! Kana iwe wakambomira kuti ufunge nezve izvo zvinoumba nyika yakatitenderedza, PVC ingangove imwe inobuda kakawanda kupfuura iwe yaunoona. Kubva papombi dzinotakura mvura mudzimba dzedu kusvika pauriri hunogara kwenguva refu mumahofisi edu, matoyi evana vedu vanotamba nawo, uye kunyange mabhachi anonaya mvura anoita kuti tirambe takaoma—PVC iri kwose kwose. Asi hechino chakavanzika chidiki: hapana chimwe cheizvi zvigadzirwa chaizobata hafu zvakare pasina chinhu chakakosha chinoshanda kuseri kwezviitiko:PVC stabilizers.
Ngatitangei nezvinokosha. PVC, kana polyvinyl chloride, chinhu chinoshamisa. Iyo yakasimba, inoshanda zvakasiyana-siyana, uye yakanyanya kuchinjika, ndosaka ichishandiswa muzvigadzirwa zvakawanda. Asi sezvinhu zvakawanda zvakanaka, ine chikanganiso chidiki: haisi fan hombe yekupisa kwakanyanya kana chiedza chezuva. Nokufamba kwenguva, kuratidzwa kune izvi zvinhu kunogona kukonzera PVC kuputsika-maitiro anonzi degradation. Izvi zvinogona kuita kuti zvigadzirwa zviite brittle, discolored, kana kuti zvisashande.
Ndipo panopindira ma stabilizers.Funga nezvavo sevarindi vePVC, vachishanda nesimba kuti irambe iri muchimiro chepamusoro. Ngatitaurei kuti nei vachinyanya kukosha: Kutanga kubva, ivo vanowedzera hupenyu hwePVC zvigadzirwa. Pasina zvigadziriso, iyo PVC pombi pasi pesingi yako inogona kutanga kutsemuka mushure memakore mashoma ekubata nemvura inopisa, kana kuti toyi yevana ine mavara inogona kupera uye kuita brittle kubva pakugara muzuva. Stabilizers inononoka kuderera kwemaitiro, zvichireva kuti zvinhu zvako zvePVC zvinogara kwenguva refu-zvichikuchengetedza mari uye kuderedza tsvina munguva refu.
Ivo zvakare vanochengeta PVC ichiita zvakanakisa. PVC inozivikanwa nekuomarara, kusimba, uye kushingirira kumoto — hunhu hwatinovimba nahwo mune zvese kubva kumafuremu emafafitera kusvika kune ekudzivirira magetsi. Stabilizers inovimbisa kuti zvivakwa izvi zvinoramba zvakamira. Fungidzira mufananidzo wePVC wehwindo unoputika mukupisa kwezhizha kana tambo yekudzivirira inorasikirwa neunhu hwayo hwekudzivirira nekufamba kwenguva-zvigadziro zvinodzivirira izvozvo. Ivo vanobatsira PVC kuchengetedza simba rayo, kuchinjika (muzvigadzirwa zvakapfava), uye kuramba kwemurazvo, saka inoita chaizvo izvo zvinofanirwa kuita, zuva nezuva.
Imwe plus huru? Stabilizers inoita kuti PVC iwedzere kuchinjika kune dzakasiyana nharaunda. Ingave zuva rinopisa richirova pasi pauriri hwekunze, tembiricha yakakwira mumaindasitiri, kana kugara uchiratidzwa hunyoro mupombi dzemvura, zvinogadzirisa zvinobatsira PVC kuti ibate. Mhando dzakasiyana dze stabilizers-secalcium-zinc, barium-zinc, kanaorganicmatani akasiyana-akagadzirirwa kugadzirisa matambudziko chaiwo, kuve nechokwadi kuti pane mhinduro kune chero mamiriro ezvinhu.
Saka, nguva inotevera paunotora chigadzirwa chePVC, tora nguva yekutenda zvigadziriso zviri kuita chinhu chavo. Vanogona kunge vasiri nyeredzi yechiratidziro, asi iwo magamba asina kusimba anoita kuti PVC ive yakavimbika, inogoneka zvinhu isu tese tinovimba nayo. Kubva pakuchengetedza dzimba dzedu nemafuremu akasimba emahwindo kusvika pakuona kuti matoyi edu anogara akachengeteka kwemakore, zvinodzikamisa ndicho chikonzero PVC ichiramba ichive chikafu munzvimbo dzakawanda dzehupenyu hwedu.
Wakambozvibvunza here kuti chaiyo PVC chigadzirwa chinogara chichitaridzika zvakanaka kwenguva yakareba kudaro? Mikana ndeyekuti, yakanaka stabilizer chikamu chemhinduro!
