IPOLYETHER POLYOL (PPG)luhlobo lwemathiriyeli yepolymer enokumelana nobushushu obugqwesileyo, ukuxhathisa kweasidi, kunye nokuxhathisa kwealkali.Isetyenziswa kakhulu kwimimandla efana nokutya, ezonyango, kunye ne-elektroniki, kwaye iyinxalenye ebalulekileyo yemathiriyeli yokwenziwa yanamhlanje.
Ngaphambi kokuthenga i-polyether, kuyimfuneko ukuqonda ukuba yintoni na.I-Polyether yimathiriyeli yeplastiki ephezulu kakhulu enokuthi ifumaneke ngokuphendula kwe-polymerization.I-polyether ineepropati eziqinileyo ezifana nokuxhathisa ubushushu, ukuxhathisa kwe-oxidation, ukuxhathisa kwe-asidi kunye ne-alkali, kunye nokumelana ne-oyile, okwenza ukuba isetyenziswe ngokubanzi kwimveliso yemveliso eyahlukeneyo kunye neyoluntu.
Ngoko ke singayithenga phi i-polyether esemgangathweni? Okwangoku, baninzi ababoneleli be-polyether, kwaye inokuthengwa ngeendlela ezahlukeneyo, ezifana ne-intanethi, iinkampani zokuguqulela kunye nabarhwebi.Xa ukhetha umthengisi, la manqaku alandelayo kufuneka aqwalaselwe:
Irekhodi yekhredithi yomthengisi
Ngaphambi kokuthenga i-polyether, kubalulekile ukuqonda irekhodi yekhredithi yomthengisi, kubandakanywa neerekhodi zabo zentengiselwano yangaphambili, ukuvavanya ukuthembeka kwazo kunye nokuqinisekisa ukhuseleko kunye nokusebenza kakuhle kokuthenga.
Umgangatho wemveliso yomthengisi
Umgangatho weIPOLYETHER POLYOL (PPG)ichaphazela ngqo ukhuseleko kunye nokusebenza kweemveliso.Ke ngoko, ukukhetha umthengisi othembekileyo kunokuqinisekisa umgangatho wemveliso kunye nokuphucula ukusebenza kwemveliso.
Inkqubo yenkonzo yomthengisi emva kokuthengisa
Ukuthenga i-polyether ayifuni kuphela umgangatho wemveliso ethembekileyo kodwa ifuna ukuba umthengisi abonelele ngexesha kunye nenkonzo yokuthengisa emva kokuthengisa ukuqinisekisa ukusetyenziswa okuqhelekileyo kweemveliso.
Emva kokuqonda indlela yokukhetha umthengisi, ungaqala inkqubo yokuthenga i-polyether.Amanyathelo okuthenga i-polyether ami ngolu hlobo lulandelayo:
Qinisekisa ubungakanani kunye neenkcukacha eziza kuthengwa
Okokuqala, misela ubuninzi kunye neenkcukacha ze-polyether eziza kuthengwa ngokusekelwe kwiimfuno zemveliso kunye neemfuno zangempela.
Qhagamshelana nomthengisi kwaye ufumane ikowuteshini
Emva kokukhetha umthengisi ofanelekileyo, qhagamshelana nabo ngefowuni, i-imeyile, okanye iiplatifomu ze-intanethi ukuze ucele ulwazi oluneenkcukacha kunye namaxabiso e-polyether.
Thelekisa iikowuti kunye neenkonzo
Emva kokufumana iikowuteshini ezivela kubaboneleli abaninzi, thelekisa amaxabiso kunye neenkonzo ezibonelelwa ngababoneleli abahlukeneyo ukuze wenze isigqibo sokuba yeyiphi enokuhlangabezana ngcono neemfuno zakho zokuthenga.
Sayina isivumelwano sokuthenga
Emva kokugqiba umthengisi, isivumelwano sokuthenga kufuneka sisayinwe ukuze kuqinisekiswe amalungelo kunye neenzuzo zamaqela omabini.
Intlawulo kunye nokuhanjiswa
Emva kokusayina isivumelwano sokuthenga, yenza intlawulo ngokwemiqathango ekuvunyelwene ngayo.Emva kokuba umthengisi efumene intlawulo, baya kulungiselela ukuthunyelwa kwe-polyether.
Isishwankathelo, ukuthengaIPOLYETHER POLYOL (PPG)kufuna umgudu kunye nexesha, kodwa nje ukuba ufumana umthengisi ofanelekileyo, unokuqinisekisa umgangatho wemveliso kunye nokusebenza.Ukongeza, kufuneka kuthathelwe ingqalelo ngononophelo ekukhetheni ababoneleli-nkonzo kunye namalungiselelo entlawulo ukuqinisekisa ukuba inkqubo yokuthenga ingenabungozi nengenaziphene.
