Sawubona! Uma wake wema ukucabanga ngezinto ezakha umhlaba osizungezile, i-PVC cishe ingenye evele kaningi kunalokho ocabanga ngakho. Kusukela kumapayipi athwala amanzi emakhaya ethu kuya phansi okuqinile emahhovisi ethu, amathoyizi izingane zethu ezidlala ngawo, ngisho namajazi emvula asigcina somile—i-PVC ikhona yonke indawo. Kodwa nansi imfihlo encane: akukho neyodwa yale mikhiqizo ebingahlala kahle ngaphandle kwesithako esiyinhloko esisebenza ngemuva kwezigcawu:Iziqinisi ze-PVC.
Ake siqale ngezinto eziyisisekelo. I-PVC, noma i-polyvinyl chloride, iyinto enhle kakhulu. Iqinile, iyasebenziseka kalula, futhi ivumelana nezimo kakhulu, yingakho isetshenziswa emikhiqizweni eminingi kangaka. Kodwa njengezinye izinto ezinhle, inephutha elincane: ayithandi ukushisa okukhulu noma ukukhanya kwelanga. Ngokuhamba kwesikhathi, ukuchayeka kulezi zinto kungabangela ukuthi i-PVC ibole—inqubo ebizwa ngokuthi ukuwohloka. Lokhu kungenza imikhiqizo ingabi bushelelezi, ishintshe umbala, noma ingasebenzi kahle.
Yilapho-ke iziqinisi zingena khona.Cabanga ngabo njengabaqaphi be-PVC, abasebenza kanzima ukuyigcina isesimweni esihle. Ake sichaze ukuthi kungani bebaluleke kangaka: Okokuqala, bandisa impilo yemikhiqizo ye-PVC. Ngaphandle kwezithambisi, lelo phayiphi le-PVC ngaphansi kwesinki yakho lingase liqale ukuqhekeka ngemva kweminyaka embalwa yokusebenzisa amanzi ashisayo, noma lelo thoyizi lezingane elinemibala linganyamalala futhi libe buthaka ngenxa yokuhlala elangeni. Izithambisi zibambezela inqubo yokuwohloka, okusho ukuthi izinto zakho ze-PVC zihlala isikhathi eside—zikongela imali futhi zinciphise imfucuza ngokuhamba kwesikhathi.
Futhi zigcina i-PVC isebenza kahle kakhulu. I-PVC yaziwa ngokuba lukhuni, iqine, futhi imelana nomlilo—izimfanelo esizithembele kuzo kukho konke kusukela ozimele bamafasitela kuya ekushiseni kukagesi. Izithambisi ziqinisekisa ukuthi lezi zakhiwo zihlala zinjalo. Cabanga ngephrofayili yefasitela le-PVC eligobeka ekushiseni kwehlobo noma ukufakelwa kwekhebula okulahlekelwa yizimfanelo zalo zokuvikela ngokuhamba kwesikhathi—izithambisi zivimbela lokho. Zisiza i-PVC ukuthi igcine amandla ayo, ukuguquguquka kwayo (emikhiqizweni ethambile), kanye nokumelana nomlilo, ngakho-ke yenza lokho okufanele ikwenze, usuku nosuku.
Okunye okuhle kakhulu? Ama-stabilizer enza i-PVC ivumelane nezimo ezihlukene. Kungakhathaliseki ukuthi ilanga elishisayo lishaya phansi ngaphandle, amazinga okushisa aphezulu ezindaweni zezimboni, noma ukuchayeka njalo emanzini kumapayipi, ama-stabilizer asiza i-PVC ukuthi ibambe indawo yayo. Izinhlobo ezahlukene zama-stabilizer—njengei-calcium-zinc, i-barium-zincnomaokungokwemveloizinhlobo zethini—zenzelwe ukubhekana nezinselele ezithile, ukuqinisekisa ukuthi kukhona ikhambi cishe lanoma yisiphi isimo.
Ngakho-ke, ngesikhathi esizayo lapho uthenga umkhiqizo we-PVC, zinike isikhashana ukwazisa izinto eziqinisayo ezenza umsebenzi wazo. Kungenzeka ukuthi aziyona inkanyezi yombukiso, kodwa zingamaqhawe angadunyiswanga enza i-PVC ibe yinto ethembekile neguquguqukayo esithembele kuyo sonke. Kusukela ekugcineni amakhaya ethu ephephile ngamafreyimu amafasitela aqinile kuya ekuqinisekiseni ukuthi amathoyizi ethu ahlala ephephile iminyaka eminingi, izinto eziqinisayo yizona ezenza i-PVC iqhubeke nokuba yinto ebalulekile ezingxenyeni eziningi zokuphila kwethu.
Wake wazibuza ukuthi umkhiqizo othize we-PVC uhlala kanjani umuhle isikhathi eside kangaka? Kungenzeka ukuthi i-stabilizer enhle iyingxenye yempendulo!
