Yintoni iPolyester Resin?
I-polyester resin luhlobo olukhethekileyo lweplastiki olusetyenziselwa izinto ezingenakubalwa. Kuba yomelele kakhulu kwaye inxibe ixesha elide, lukhetho oludumileyo kwiimveliso ezininzi. Ngombulelo kwezi zakhiwo zibalaseleyo, ingasetyenziselwa ifenitshala, izinto zemoto, izikhephe kunye nokunye. Kodwa ngomonde, ukwenza i-polyester resin isebenze ngcono, sisebenzisa i-catalyst.
Yintoni iCatalyst?
I-catalyst yekhemikhali inokuchazwa njengento ekhawulezisa ukusabela kweekhemikhali. Ingumncedi wokusabela, kodwa ayingeni naluphi na utshintsho ngokwayo kwinkqubo. I-catalyst ixutywe kwi-polyester resin ukuguqula uhlobo lwe-resin elulwelo lube luqilima. Kubalulekile kuba ibangela ukuba i-resin ilungele ukusetyenziswa. Ukuba asisebenzisi i-catalyst efanelekileyo, i-resin ayiyi kunyanga ngokupheleleyo. Oku kunokubangela imiba efana nokuba buthathaka kakhulu okanye ukungabambeleli kakuhle kwezinye izinto, nto leyo eguqulela ekubeni yimveliso engasebenzi kakuhle.
Ukukhetha i-Catalyst eLungileyo
Kwaye ukuze i-polyester resin isebenze ngokusemandleni ayo, kufuneka sikhethe i-catalyst efanelekileyo yomsebenzi. Ii-catalysts ezahlukeneyo zinemisebenzi eyahlukeneyo. Nangona kunjalo, ezinye ii-catalysts zigqwesa nje ukudibanisa i-resin ngokukhawuleza. Abanye bancedisa kwimichiza ebangela ukuba i-resin ibe yomelele kwaye yomelele ngakumbi. Oku kusinika ingqiqo esiyidingayo ukuze senze izigqibo ezingcono kwiiprojekthi zethu.
Izixhobo zokuhlela iiPropati zePolyester Resin
Sijonga into esifuna ukuyiphucula kwi-resin xa sikhetha i-catalyst. Njengaye, ukuba sifuna i-resin imelane nobushushu-njengakwimoto eshushu kakhulu-besiya kukhetha into ebizwa ngokuba yi-cobalt naphthenate. Le catalyst inceda ukwenza intlaka ekwaziyo ukumelana nobushushu. Ngokuchaseneyo, ukuze intlaka ibambelele kwizinto, sinokusebenzisa ikhompawundi efana ne-benzoyl peroxide. I-resin ephethwe yi-catalyst ibambelela kakuhle kwii-substrates ezininzi. Ukukhetha i-catalyst efanelekileyo kuguqula kakhulu amandla kunye nokuqina kwe-resin ukuze isebenze ngakumbi kweso sicelo.
i-polyester resin
Ukongeza i-catalyst yenye yezona zinto zibalulekileyo xa kuziwa ekwenzeni i-polyester resin yomelele. Kukho ezinye ii-catalysts ezinokuthi zongezwe kwi-resin ukuyinceda ibe lukhuni kwaye yomelele ngakumbi. Umzekelo, i-catalyst ebizwa ngokuba yi-triethylenediamine (TEDA) inokudityaniswa kwi-resin ukuqinisa amandla. Oku kunjalo ke imveliso egqityiweyo iya kuba yomelele ngakumbi kwaye ihlala njalo. Ezinye iintlobo - njenge dibenzoyl peroxide, iperoxide ephilayo - ingadityaniswa kumxube ukwenza intlaka ibenzima kwaye inganyangeki. Ii-catalysts ezifanelekileyo zomeleza uyilo oluqhelekileyo lwe-polyester resin ngaloo ndlela lwenza ukuba lufaneleke kwizicelo ezininzi.
Kutheni iiCatalysts zibalulekile
Ngamafutshane, ukusebenzisa i-catalysts ezichanekileyo kuphela kunokunyusa amandla kunye nokusetyenziswa kwe-polyester resin eninzi. Ukuqonda ukuba siza kuyisebenzisa njani i-resin, kwaye apho sifuna ukubona ukuphuculwa, ngundoqo apha. Oku kuya kusivumela ukuba senze ezinye izinto zokugalela intlaka yepolyester, njengeemoto, iinqwelo-moya, izikhephe, izinto zokwakha, nezixhobo zombane zibe bhetele ngakumbi ngokukhetha ngokucingisisayo isixhobo esinamandla. I-Lingshi lishishini elidumileyo elibandakanyeka ekuveliseni izixhobo ezikumgangatho ophezulu we-polyester resin. Ii-catalysts zabo ezahlukeneyo zinokulungiswa ukuze zihambelane neemfuno ezahlukeneyo, kwaye zincede ukuqhuba umgangatho kwi-resin. Ukusuka apha, i-polyester resin inokwenziwa ngcono kuzo zonke iintlobo zeeprojekthi kwaye uLingshi ligama elithembekileyo ukwenza oko ngolwazi lwabo kunye nokuzinikela kumgangatho.
