Kubakhiqizi be-PVC, ukuthola isiqinisi esilinganisela ukusebenza, ukucutshungulwa, kanye nokusimama sekuyisikhathi eside kuyinto enzima. Imikhiqizo eqinile ye-PVC efana nozimele befasitela, amaphaneli eminyango, kanye namaphrofayili okwakha idinga ukumelana nokushisa okuqhubekayo, ukuqeda okubushelelezi kobuso, kanye nokuhambisana nemithetho eqinile yezemvelo—konke lokhu kugcina ukukhiqiza kusebenza kahle futhi kungenazo iziphambeko.iziqinisi eziyinkimbinkimbi ze-calcium-zinc (Ca-Zn): ikhambi elishintsha umdlalo elibhekana nezinselele ezibalulekile embonini ngenkathi livula amathuba amasha okukhiqiza i-PVC esezingeni eliphezulu.
Ubuchwepheshe Obungemuva Kwama-granules: Kungani Ifomu Libalulekile
Ngokungafaniiziqinisi eziphuphuthekileEzingcolile, okunzima ukuzilinganisa, noma ezivame ukugoqana, iziqinisi ze-Ca-Zn ezihlanganisiwe zenzelwe ukunemba. Usayizi wazo wezinhlayiya ezifanayo uqinisekisa ukuhlanganiswa okulula kuma-compound e-PVC, okususa inkinga yokuhlakazeka okungalingani—okuyimbangela evamile yokungahambisani komkhiqizo. Kodwa izinzuzo zobuchwepheshe zidlula ukuphathwa:
• Ukuqina Kokushisa Okuphezulu:Kubalulekile ekucutshungulweni kwe-PVC okuqinile (isb., ukukhipha, ukubumba ngemijovo), lezi ziqinisi ziyamelana nokuwohloka kokushisa ngesikhathi sokukhiqizwa kwezinga lokushisa eliphezulu, zivimbela ukushintsha kombala kanye nobuthakathaka besakhiwo emikhiqizweni yokugcina.
• Ukugeleza Okuthuthukisiwe:Ifomu le-granular linciphisa ukungqubuzana phakathi kwezinhlayiya ze-resin ze-PVC, lithuthukisa ukugeleza kokuncibilika ngesikhathi sokucubungula. Lokhu akusheshisi nje kuphela imijikelezo yokukhiqiza kodwa futhi kuletha izindawo ezibushelelezi kumaphrofayili nasemaphaneli—akusekho imiphetho eqinile noma amabala ebusweni.
• Ukuthamba Okungaphakathi:Inzuzo ebalulekile yezinto zokwakha, izakhiwo zokugcoba eziyisisekelo zeziqinisi zenza kube lula ukwenziwa, okuvumela ukubumbana okungenamthungo kwezingxenye eziyinkimbinkimbi ze-PVC ngaphandle kokunamathela emishinini.
Izicelo Ezihlukahlukene: Kusukela Ekwakhiweni Kuya Ngaleyo
Iziqinisi ze-Granular Ca-Zn zikhanya kakhulu ekukhiqizweni kwe-PVC eqinile, lapho ukusebenza kwazo kuthinta ngqo ukuqina komkhiqizo kanye nobuhle. Amafreyimu amafasitela namaphaneli eminyango, isibonelo, athembele ekuzinzeni kwawo kokushisa ukuze amelane nezimo zezulu ezinzima ngokuhamba kwesikhathi, kuyilapho amaphrofayili okwakha ezuza ekuhlakazekeni okuqhubekayo ukuze alondoloze ubuqotho besakhiwo. Kodwa ukuguquguquka kwawo akugcini lapho—futhi afaneleka kakhulu kumapayipi e-PVC, izinto zokufakelwa, ngisho nokuhlobisa, okuzivumelanisa nezindlela ezahlukene zokucubungula ngaphandle kokubeka engcupheni ikhwalithi.
Kubakhiqizi abahlose izimakethe zezakhiwo eziluhlaza, lezi ziqinisi ziyindlela yokuwina ukuhambisana nemithetho: ngokungafani nezinye izindlela ezisekelwe kunsimbi esindayo (isb., iziqinisi ze-lead noma ze-cadmium), zinobungani nemvelo, azinabo ubuthi, futhi zihlangabezana nezindinganiso zemvelo zomhlaba wonke (njengemithetho ye-EU REACH kanye ne-US EPA). Lokhu kuzenza zibe yisinqumo esithandwayo semikhiqizo ebeka phambili ukusimama ngaphandle kokulahlekelwa ukusebenza.
Abakhiqizi Bokuxazulula'Amaphuzu Aphezulu Obuhlungu
Abakhiqizi be-PVC babhekene nezinselele ezihlukile ezingaphazamisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo. Nansi indlela iziqinisi ze-Ca-Zn ezihlanganisiwe ezibhekana ngayo nezinkinga ezibucayi kakhulu:
▼ Iphuzu Lobuhlungu 1: Ukuhlakazeka Okubi Okuholela Emaphutheni
Izithambisi ezingasabalaliswanga ngokungalingani zibangela izindawo ezishisayo, ukushintsha kombala, kanye namabala aqhekekayo emikhiqizweni ye-PVC—okubiza abakhiqizi isikhathi nemali ngokuvuselela. Isixazululo: Ifomethi ye-granular iqinisekisa ukuxubana okufanayo ne-resin ye-PVC, ngisho nasezintweni ezikhipha i-extruder ngesivinini esikhulu. Abakhiqizi abasadingi ukutshala imali emishinini yokuxuba eyengeziwe noma ukwandisa isikhathi sokucubungula;iziqinisiukusabalala njalo, kunciphisa amazinga okukhubazeka kakhulu.
▼ Iphuzu Lobuhlungu 2: Ukusebenza Kahle Kwenqubo Okuphansi Ngenxa Yokugeleza Okubi
Ama-compound e-PVC anamathelayo anciphisa ukukhiqizwa, abangela ukuguguleka komshini, futhi abangela ukungalingani kobukhulu bomkhiqizo. Isixazululo: Iziqinisi ze-Granular Ca-Zn zithuthukisa ukugeleza kokuncibilika ngokunciphisa ukungqubuzana kwangaphakathi. Lokhu kuvumela isivinini esisheshayo somugqa, izikhathi zomjikelezo ezimfushane, kanye nesikhathi esincane sokungasebenzi sokuhlanza umshini—okukhulisa umkhiqizo jikelele ngamaphesenti afinyelela ku-15 (ngokusekelwe ezilinganisweni zomkhakha).
▼ Iphuzu Lobuhlungu 3: Izingozi Zokuthobela Imithetho Yemvelo
Izithambisi zensimbi esindayo zibhekene nokuvinjelwa okwandayo emhlabeni wonke, okushiya abakhiqizi besengozini yokuthola izinhlawulo ezisemthethweni kanye nomonakalo wedumela. Isixazululo: Njengoba zingenazo izinsimbi ezisindayo eziyingozi, izithambisi ze-Ca-Zn ezihlanganisiwe zisusa izingozi zemvelo. Kulula ukuzihlanganisa emigqeni yokukhiqiza ekhona (asikho isidingo sokuthuthukiswa kwemishini ebizayo) futhi zisiza izinkampani ukuthi zihlangabezane nemigomo yokusimama ngenkathi zihlala zithobela imithetho.
▼ Iphuzu Lobuhlungu 4: Ubunzima Ekulinganisweni Okunembile
Iziqinisi ezifakwe ufulawa kunzima ukuzilinganisa ngokunembile, okuholela ekusetshenzisweni ngokweqile (ukwandisa izindleko) noma ukusetshenziswa okunganele (ukuzinza okuphazamisayo). Isixazululo: Izinhlayiya ze-granular kulula ukuzilinganisa ngemishini yokudla ejwayelekile, okuqinisekisa ukulawulwa okunembile kwamazinga okwengezwa (ngokuvamile ama-PHR angu-3-5). Lokhu akugcini nje ngokunciphisa imfucuza yezinto ezibonakalayo kodwa futhi kugcina ikhwalithi yomkhiqizo ihambisana njalo ngemva kweqoqo.
Kungani Izithambisi ze-Granular Ca-Zn Ziyikusasa le-PVC
Emakethe lapho ukusebenza kahle, ukusimama, kanye nekhwalithi kungaxoxiswana ngakho, iziqinisi ze-calcium-zinc complex ezihlanganisiwe zihlola wonke amabhokisi. Zixazulula izinkinga zokukhiqiza esezinesikhathi eside, zivumelanise nezinhlelo zokusebenza ze-PVC eziqinile ezahlukahlukene, futhi zihambisana noshintsho lomkhakha oluya ekukhiqizeni okunobungani nemvelo. Kubakhiqizi abafuna ukuhlala bencintisana, lobu buchwepheshe abuyona nje intuthuko—buyimfuneko.
Kungakhathaliseki ukuthi wenza amaphrofayili okwakha, ozimele bamafasitela, noma izinto zokufaka ze-PVC, iziqinisi ze-Ca-Zn ezihlanganisiwe ziletha ukuthembeka nokusebenza okudingekayo ukuze zivelele emakethe egcwele abantu. Njengoba imithethonqubo yezemvelo iqina futhi isidingo sabathengi semikhiqizo esimeme sikhula, lezi ziqinisi zizoqhubeka nokuba yisinqumo esithandwayo sokucabanga kusengaphambili.Abakhiqizi be-PVC.
Uke wabhekana nezinselele zokusabalala, ukusebenza kahle kwenqubo, noma ukuhambisana nomthetho ekukhiqizweni kwakho kwe-PVC? Yabelana ngemicabango yakho kumazwana—noma xhumana nathi ukuze ufunde ukuthi iziqinisi ze-Ca-Zn ezihlanganisiwe zingalungiswa kanjani ukuze zivumelane nomsebenzi wakho othize!
