1. Kusekho i-gap ethile phakathi kwe-PVC yasekhaya yokuncedisa izixhobo kunye neemveliso zangaphandle, kwaye amaxabiso aphantsi awanayo inzuzo enkulu kukhuphiswano lwemarike.
Nangona iimveliso zasekhaya zineenzuzo ezithile ngokwejografi namaxabiso kukhuphiswano lweemarike, sinezikhewu ezithile ekusebenzeni kwemveliso, iintlobo ngeentlobo, uzinzo, kunye neminye imiba xa kuthelekiswa neemveliso zangaphandle. Oku kunxulumene nokubuyela umva kwefomula yemveliso yethu, itekhnoloji yokucubungula, ukusetyenzwa, kunye nobuchwepheshe basemva konyango. Amanye amashishini asekhaya ayazi ngokupheleleyo le miba kwaye aseke ubudlelwane bentsebenziswano kunye namaziko ophando, amaziko ophando kunye nophuhliso, kwaye aqhuba uphando malunga nezongezo zeplastiki.
2. Iifektri ezincinci zahlukene kwaye akukho shishini likhokelayo elinesikhundla esipheleleyo, esikhokelela kukhuphiswano olungalunganga kwimarike.
Okwangoku, kukho malunga nama-30 abenzi be-ACR basekhaya, kodwa kuphela aba-4 kubo banemveliso enkulu (enomthamo wokufakelwa konyaka ongaphezu kweetoni ezingama-5000). Iimveliso zala mashishini amakhulu ziye zaseka umfanekiso omhle kwiimarike zasekhaya nezamazwe ngamazwe, kungakhathaliseki ukuba zeziphi iindidi zemveliso kunye nomgangatho. Kodwa kule minyaka mibini idlulileyo, ngokuchuma kweshishini lokulungisa le-PVC, ezinye iifektri ezincinci ze-ACR ezinomthamo wemveliso ongaphantsi kweetoni ezili-1000 ziye zagxalathelana ukuya emarikeni. Ngenxa yezixhobo zabo zemveliso ezilula kunye nozinzo olulambathayo lwemveliso, la mashishini anokuphila kuphela ngokusebenzisa ukulahla okunexabiso eliphantsi, okukhokelela kukhuphiswano oluqatha kwimarike yasekhaya. Ezinye iimveliso ezikumgangatho ophantsi kunye nomgangatho ophantsi zakhukulisa imarike ngoko nangoko, zizisa iziphumo ezibi kumashishini okulungisa asezantsi kwaye zizisa neempembelelo ezingalunganga kuphuhliso loshishino. Kucetyiswa ukuba i-Plastic Processing Association ikhokele ekusekeni i-ACR Additive Industry Association, idibanise imigangatho yoshishino, ilawule uphuhliso lweshishini, isuse imveliso yomgunyathi kunye neemveliso eziphantsi, kwaye inciphise ukhuphiswano olungahambi kakuhle. Kwangaxeshanye, amashishini amakhulu kufuneka anyuse iinzame zawo zophuhliso lwemveliso, ahlengahlengise ubume bemveliso yawo, kwaye agcine uphuhliso oluhambelanayo kunye neemveliso ezifanayo zangaphandle.
3. Ukunyuka kwamaxabiso e-oyile ekrwada kukhokelele ekunyukeni kwamaxabiso ezinto ezikrwada kunye nokwehla kweengeniso zeshishini.
Ngenxa yokunyuka okuqhubekayo kwamaxabiso e-oyile ekrwada kumazwe ngamazwe, zonke ezona zixhobo ziphambili zemveliso ye-ACR, i-methyl methacrylate kunye ne-acrylic ester, ziye zanyuka. Nangona kunjalo, abathengi abasezantsi basala ngasemva ekunyukeni kwamaxabiso emveliso, okukhokelele ekwehleni ngokubanzi kwengeniso kumashishini okulungisa i-ACR. Oku kuye kwakhokelela kwimeko yokulahlekelwa kwishishini lonke kwi-2003 kunye ne-2004. Okwangoku, ngenxa yokuzinzisa kwamaxabiso ezinto eziphathekayo, ishishini libonise umgangatho omhle wokufumana inzuzo.
4. Ukunqongophala kweetalente zobungcali, uphando loshishino alukwazanga ukuphuhlisa ngokunzulu
Ngenxa yokuba isongezelelo se-ACR sisongezo se-polymer esaphuhliswa kuphela e-China ngasekupheleni kweminyaka yoo-1990, iiyunithi zophando nophuhliso kunye nabaphandi bambalwa xa kuthelekiswa nezinye izongezo ezifana neeplastiki kunye ne-flame retardants e-China. Nokuba kukho amaziko ophando azimeleyo aphuhlisayo, ukungabikho kokudityaniswa okuhle phakathi kwabaphandi kunye neshishini lokulungisa iplastiki kubangele ukungakwazi ukwenza nzulu uphando lwemveliso. Okwangoku, uphuhliso lwe-ACR e-China luxhomekeke kuphela kumaziko ophando aphethwe ngamashishini ambalwa ukuba aququzelele kwaye aphuhlise. Nangona kukho impumelelo eyenziweyo, kukho umsantsa omkhulu phakathi kwabalingane basekhaya nabangaphandle ngokwenkxaso-mali yophando, izixhobo zophando kunye nophuhliso, kunye nophando kunye nomgangatho wophuhliso. Ukuba le meko ayiphuculwanga ngokusisiseko, kuya kungaziwa ukuba izixhobo zokuncedisa zingama ziqinile kwimarike yasekhaya kwixesha elizayo.
