Molo apho! Ukuba ukhe wema ukuba ucinge ngezinto ezenza ihlabathi elisijikelezileyo, iPVC mhlawumbi yenye ethi ivele rhoqo kunokuba ucinga. Ukususela kwimibhobho ehambisa amanzi emakhayeni ethu ukuya kumgangatho oqinileyo kwiiofisi zethu, izinto zokudlala abantwana bethu abadlala ngazo, kwaneebhatyi zemvula ezisigcina somelele—iPVC ikuyo yonke indawo. Kodwa nantsi imfihlo encinci: akukho nanye kwezi mveliso inokubamba isiqingatha ngaphandle kwesithako esiphambili esisebenza emva kwezigcawu:PVC izinzisi.
Masiqale ngezinto ezisisiseko. I-PVC, okanye i-polyvinyl chloride, yinto emangalisayo. Yomelele, iyaguquguquka, kwaye iguquguquka kakhulu, yiyo loo nto isetyenziswa kwiimveliso ezininzi. Kodwa njengezinto ezininzi ezilungileyo, inesiphako esincinci: ayikuthandi ubushushu obugqithisileyo okanye ukukhanya kwelanga. Ngokuhamba kwexesha, ukuvezwa kwezi zinto kunokubangela ukuba i-PVC idilize-inkqubo ebizwa ngokuba yi-degradation. Oku kunokwenza ukuba iimveliso zibe-brittle, zibe nombala, okanye zingasebenzi kakuhle.
Kulapho izinzisi zingenelela khona.Cinga ngabo njengabagcini bePVC, abasebenza nzima ukuyigcina ikwimo ephezulu. Makhe sichaze ukuba kutheni zibaluleke kangaka: Okokuqala, zandisa ubomi beemveliso zePVC. Ngaphandle kozinzisi, loo mbhobho wePVC phantsi kwesinki yakho unokuqalisa ukuqhekeka emva kweminyaka embalwa yokujongana namanzi ashushu, okanye loo nto yokudlala yabantwana enemibala inokuphela kwaye ibe brittle ngokuhlala elangeni. Izinzisi zicotha inkqubo yokuthotywa, oku kuthetha ukuba izinto zakho zePVC zihlala ixesha elide-ukugcina imali kunye nokunciphisa inkunkuma ekuhambeni kwexesha.
Bakwagcina iPVC isenza okona kulungileyo. I-PVC yaziwa ngokuba ngqongqo, yomelele, kwaye imelane namadangatye-iimpawu esithembele kuzo kuyo yonke into ukusuka kwifreyimu zefestile ukuya kwi-insulation yombane. Izinzisi ziqinisekisa ukuba ezi zakhiwo zihlala zinjalo. Khawucinge ngeprofayili yefestile ye-PVC ephazamisayo ekushiseni kwehlobo okanye i-cable insulation elahlekelwa yimpawu zayo zokukhusela ngexesha-i-stabilizers iyayinqanda loo nto. Banceda i-PVC igcine amandla ayo, ukuguquguquka (kwiimveliso ezithambileyo), kunye nokuxhathisa idangatye, ngoko ke yenza kanye le nto imele ukuba iyenze, imini nemini.
Enye into enkulu? Izinzisi zenza i-PVC ilungelelanise ngakumbi kwiindawo ezahlukeneyo. Nokuba lilanga eligqats’ ubhobhoyi elibetha phantsi kumgangatho wangaphandle, amaqondo obushushu aphezulu kwiindawo zemizi-mveliso, okanye ukuchanabeka rhoqo kubumanzi kwimibhobho yamanzi, izizinzisi zinceda i-PVC ibambe umhlaba. Iindidi ezahlukeneyo zokuzinzisa-ezifanacalcium-zinc, i-barium-zinc, okanyeeziphilayoiintlobo zetoti-ziyilelwe ukujongana nemingeni ethile, ukuqinisekisa ukuba kukho isisombululo phantse kuyo nayiphi na imeko.
Ke, kwixesha elizayo xa uthatha imveliso yePVC, thatha umzuzwana ukuxabisa abazinzileyo benza into yabo. Basenokungabi yinkwenkwezi yomboniso, kodwa bangamagorha angazange adunyiswe enza i-PVC ibe yinto enokuthenjwa, enezinto ezininzi esixhomekeke kuzo. Ukusuka ekugcineni amakhaya ethu ekhuselekile ngezakhelo zefestile ezomeleleyo ukuya ekuqinisekiseni ukuba iithoyi zethu zihlala zikhuselekile iminyaka, izinzisi sesona sizathu se-PVC siqhubeka sisisiseko kwiindawo ezininzi zobomi bethu.
Ngaba wakha wazibuza ukuba imveliso ethile yePVC ihlala ijongeka njani ixesha elide kangaka? Amathuba kukuba, ukuzinza okulungileyo yinxalenye yempendulo!
