Ulwazi olusisiseko lwenkqubo yemveliso yePVC

Iingxaki ekufuneka zinikwe ingqalelo kwizixhobo zokudibanisa

Kwinkqubo yentlaka ye-PVC, izongezo ezahlukeneyo kufuneka zongezwe ukuphucula ukusebenza kwePVC ukuhlangabezana neemfuno zokwenza nokusebenza kwemveliso. Kwimveliso yeeplastiki zeminyango kunye neefestile zeefestile, kuyimfuneko ngokubanzi ukongeza izinto zokuqinisa ubushushu, ukulungisa izinto, izinto ezinokuguqula iimpembelelo, izinto zokuthambisa, izinto zokuzinzisa ukukhanya, iifiller kunye nee-pigment. Nangona inani lezongezelelo longeziwe yi-0.1% ukuya kwi-10% yerein yePVC, iindima zazo zibaluleke kakhulu. Kunokuthiwa akukho namnye kubo obalulekileyo, kwaye utshintsho lwexabiso elongeziweyo kunempembelelo enkulu ekusetyenzisweni nasekusebenzeni kwemveliso yokugqibela. Kukhulu. Ke ngoko, ayizizithako kuphela ekufuneka zilinganiswe ngokuchanekileyo, kodwa inkqubo yokuxuba kufuneka ixutywe ngokulinganayo ukufezekisa ukungqinelana kwezixhobo.

Ukulungiselela izinto

Inkqubo yokulungiselela izinto zePV ikakhulu kubandakanya ukubheja, ukuxuba okushushu, ukubanda okubandayo, ukuthuthwa kunye nokugcinwa. Ezi ndlela zibandakanya iindlela zokuvelisa ezincinci zokubheja ngesandla kunye nokuhambisa ngesandla, kunye neendlela zokuvelisa ezinkulu zokubhayiza okuzenzekelayo kunye nokuhamba okuzenzekelayo. Kwiminyaka yakutshanje, icandelo le-PVC yelizwe lam elikhutheleyo lokungena kwi-extrusion lingene kwixesha lokukhula ngokukhawuleza. Isikali senkampani siyaqhubeka nokwanda. Kwiinkampani ezinesiphumo sonyaka seetoni ezili-10 000, ukusetyenziswa kwezixhobo ezingezizo ezokulungisa izinto akunakuphinda kufezekise iimfuno zemveliso yobuninzi. Inkqubo yokuzenzekelayo sele iyindlela eqhelekileyo esetyenziswayo. Indlela ezenzekelayo yokulungisa izinto ngokubanzi ilungele ukuvelisa iiprofayili zezityalo ezinomthamo wemveliso ongaphezulu kweetoni ezingama-5 000. Amandla ayo asezantsi, imeko yemveliso ilungile, kwaye iimpazamo zabantu zinokuphetshwa, kodwa utyalo-mali lukhulu, inkqubo yokugcina iindleko iphezulu, ukucoca inkqubo kunzima, kwaye ifomula ayifanelekanga Utshintsho rhoqo, ngakumbi umbala utshintsho. Amashishini anomthamo wemveliso ongaphantsi kweetoni ezingama-4,000 ahlala esebenzisa izinto ezenziwe ngezandla, ezothutho kunye nokuxuba. Ingxaki enkulu yezithako ezingezizo kukuqina okukhulu kwabasebenzi, ungcoliseko lothuli lwenziwa kwizithako kunye nokuxubeka, kodwa utyalo-mali lincinci kwaye imveliso iyaguquguquka.

Ukuzenzekelayo kokulungiswa kwezinto kubhekisa kwinkqubo yokubamba ezilawulwa yikhompyuter njengeyona nto iphambili, incediswa kukuhambisa umoya, emva koko idityaniswe nabaxube abashushu nabandayo ukwenza umgca opheleleyo we-PVC kunye nokuxuba umgca wemveliso. Obu buchwephesha buchazelwe ilizwe lethu phakathi kwiminyaka yoo-1980 kwaye babusetyenziswa kwamanye amashishini amakhulu ezinga elithile. Izibonelelo zale teknoloji kukuchaneka kokubhabha okuphezulu, ukusebenza kakuhle kwemveliso, kunye nongcoliseko oluncinci, olunokuhlangabezana neemfuno zemveliso yokukhutshwa ngobuninzi. Okwangoku, ezinye iifektri kwilizwe lethu zinokuvelisa olu hlobo lwenkqubo yokulawulwa okuzenzekelayo kwekhompyuter.

Izithako yinkqubo yokuqala yokuxuba. Isitshixo sezithako ligama elithi "quasi". Kumashishini amakhulu anamhlanje avelisa iiprofayili zeplastikhi, uninzi lwezithako zamkela inkqubo elawulwa ngekhompyuter elawulwa ngamacandelo amaninzi. Eyona ndlela isetyenziswa ngokubanzi inobunzima bokulinganisa. Ngokweendlela ezahlukeneyo zobunzima, inokwahlulwa-hlulwa ngokwamacandelo obunzima obonyukayo, ilahleko-kubunzima bokulinganisa kunye nokuqhubeka kokulinganisa kwenkqubo yokuhamba kwezinto. Le ndlela yokulinganisa ibhetshi ukuya kwibhetshi iyahambelana kakhulu nendlela yokutya kunye nokuxuba ibhetshi kunye nendlela yokusebenza efunekayo kwinkqubo yokuxuba, kwaye yeyona ilungele ukudityaniswa kwePVC, ke isetyenziswa ngakumbi kwimveliso yePVC. iinkangeleko.
