Esona sizathu siphambili sokuba kutheni iPVC inezi nzuzo zimbini yinkqubo yayo yokuvelisa.Inkqubo yokuveliswa kweengxowa zePVC ayinzima.Umgca wemveliso jikelele ngokubanzi uqulunqwe ngumatshini we-roller, umatshini wokushicilela, umatshini wokugubungela umva kunye nomatshini wokusika.Ifilimu encinci idliwe kunye kwaye iphethini iprintwa kwicala langaphambili lefilimu ngumatshini wokushicilela, kunye noluhlu lwe-back coating lufakwe kwi-different yefilimu nge-back coater.
Lo maleko wokugquma ngasemva ubonakala ulinyathelo elincinci kakhulu, kodwa ngokuqinisekileyo libaluleke kakhulu kwaye liyimfuneko.Isiqinisekiso esibalulekileyo somsebenzi wesikhwama sePVC.
Ukugquma ngasemva kuqulethwe ngezinto ezikhethekileyo kwaye luhlobo lwe-agent ehambelana namandla aphezulu.Kuchanekileyo ngenxa yolu luhlu lwangasemva ukuba ifilimu ye-PVC inokudibaniswa ngokuqinileyo kunye ne-MDF okanye ezinye iibhodi, kwaye inetalente yokunyanzelisa ixesha elide elingavuli.Ingxaki ngemaski ngokubanzi kukuba ayinakujongana nengxaki yokubuna kwefilimu.
Ingxowa yokupakisha yePVC yenziwe ngezinto ezikhenkcezayo zePVC, ezintle nezihlala ixesha elide, kulula ukuyisebenzisa, zithambile ukubamba, kwaye ziyafikeleleka.Yenziwe nge-PVC ephezulu ebonakalayo, izinto ezikhethekileyo ezichasene ne-static, isikhwama asinamathelisi, kulula ukuyisebenzisa, ukusebenza kakuhle, akukho mbombo. ukutywina kucinezelekile kwaye akuqhawuki lula.Lukhetho lokupakishwa kwentengiso yazo zonke iintlobo zempahla yangaphantsi, iikawusi, amaxwebhu, izinto zokuthambisa, iimpahla zasekhaya, amalaphu asekhaya njalo njalo.
Umgangatho wokutya uquka umbala, incasa, ixabiso lesondlo, ukumila, ubunzima, kunye nezalathisi zokucoceka kokutya.Phantse konke ukutya okucoliweyo kufuneka kupakishwe phambi kokuba kuthengiswe njengempahla yorhwebo.Nangona ukutya kuyimveliso enomgangatho wayo osesichengeni sokuwohloka ngenxa yeemeko zokusingqongileyo, ukutya ngakunye okupakishweyo kufuneka kuhambelane nesalathiso somgangatho ohambelanayo weengxowa zokupakishwa kokutya kwixesha elimiselweyo.
Ikhonkco lonke lokujikeleza kokutya ukusuka ekusetyenzweni kwezinto ezikrwada ukuya ekusetyenzisweni lintsonkothile kwaye liyaguquka.Iya kuchaphazeleka kwi-biological and chemical infestation, kunye nezinto ezahlukeneyo zokusingqongileyo ezifana nokukhanya, ioksijini, ukufuma, ubushushu, kunye ne-microorganisms ebonakala ngexesha lokuvelisa kunye nenkqubo yokujikeleza.Impembelelo.
Isiphumo sokukhanya kumgangatho wokutya
(1) Ukonakala kokukhanya ekutyeni
Ukukhanya kunempembelelo enkulu kumgangatho wokutya.Inokubangela kwaye ikhawulezise ukubola kwezondlo ekudleni, kwaye ukusabela kokonakala kokutya kwenzeka.Ibonakaliswa ikakhulu kwiinkalo ezine: ukukhuthaza ukusabela kwe-oxidation yeoli ekutyeni kwaye kubangele i-oxidative rancidity;yenza ukutya Ii-pigments kwimveliso ziye zitshintshe iikhemikhali kwaye zitshintshe umbala;yenza okuluhlaza, ophuzi, obomvu ekutya kwezityalo kunye nobomvu ekudleni kwenyama emnyama okanye emdaka;kubangela ukutshatyalaliswa kweevithamini ezinokukhanya okukhanyayo ezifana neevithamini ze-B kunye neevithamini, kunye nokudibanisa nezinye izinto Utshintsho lweekhemikhali ezingathandekiyo lwenzeka;kubangela ukuguqulwa kweprotheyini kunye ne-amino acids ekutyeni.
(2) Umthetho wokungena kokukhanya ekutyeni
Ukukhanya kunokukhuthaza ngaphakathi kokutya-uluhlu lweenguqu ngenxa yamandla aphezulu.Ngaphantsi kokukhanya, iinxalenye ezingevayo kukukhanya ekutyeni zinokufunxa ngokukhawuleza kwaye ziguqule amandla okukhanya, ngaloo ndlela zivuselela ukusabela kwemichiza okwenzeka ngaphakathi kokutya.Okukhona ukutya kutsala amandla okukhanya kunye nokugqithisela okunzulu, ngokukhawuleza kwaye kuyingozi ngakumbi ukutya kuya kusonakala.Ubungakanani bamandla okukhanya afunxa kukutya bubonakaliswa kukuxinana kwamehlo.Okukhona kuphezulu ukuxinana kwamehlo, kokukhona amandla okukhanya makhulu, kwaye kokukhona ifuthe lomelele ekuwohlokeni kokutya.
