Polyether Polyol (PPG)Luhlobo lwezinto ze-polymer ngokuchasene nobushushu obuhle, ukunganyangeki kwe-asidi, kunye nokuxhathisa ialkali. Isetyenziswe ngokubanzi kwimihlaba enjengokutya, ezonyango, kunye ne-elektroniki, kwaye yinxalenye ebalulekileyo yezixhobo zentshukumo yanamhlanje.
Ngaphambi kokuba uthenge iPolyer, kuyimfuneko ukuze uqonde ukuba yintoni. I-Polyter yinto yeplasitiki yeplasitiki enokufumaneka ngokusebenza kwePolymerizaration. I-Polyter ineepropathi ezomeleleyo ezinjengokungaxhathisi ubushushu, ukumelana ne-oxidation, i-AID no-Alid no-Alkali kunye nokuxhathisa kweoyile, ukwenza ukuba isetyenziswe ngokubanzi ekwenzeni imveliso eyahlukeneyo yemizi-mveliso neyaseburhulumenteni.
Ke singayithenga phi iPolyteti elungileyo? Okwangoku, baninzi abathengisi beePolyteter, kwaye banokuthengwa ngeendlela ezahlukeneyo, njengeenkampani ze-Intanethi, nabarhwebi. Xa ukhetha umthengisi, la manqaku alandelayo makathathelwe ingqalelo:
Ingxelo yekhredithi yomthengisi
Ngaphambi kokuba uthenge iPolyer, kubalulekile ukuqonda irekhodi letyala labathengisi, kubandakanya neerekhodi zabo zentengiselwano yethutyana, ukuvavanya ukuthembeka kwabo kunye nokuqinisekisa ukhuseleko kunye nokusebenza kwempumelelo.
Umgangatho wemveliso yomthengisi
Umgangatho wePolyether Polyol (PPG)ichaphazela ngokuthe ngqo ukhuseleko kunye nokusebenza kweemveliso. Ke ngoko, ukukhetha umthengisi onokuthenjwa unokuqinisekisa umgangatho wemveliso kunye nokuphucula ukusebenza kwemveliso.
Inkqubo yomthengisi wasemva kwentengiso
Ukuthenga i-polyer ayifuni kuphela umgangatho wemveliso ethembekileyo kodwa ifuna ukuba umthengisi anikezele ngexesha elifanelekileyo kunye nenkonzo yentengiso emva kokuthengisa ukuqinisekisa ukusetyenziswa kweemveliso eziqhelekileyo.
Emva kokuqonda indlela yokukhetha umthengisi, ungaqala inkqubo yokuthengwa kwempahla yePolytere. Amanyathelo okuthenga uPollyer alandelayo:
Chonga ubungakanani kunye neenkcazo ezithengwayo
Okokuqala, chonga ubungakanani kunye neenkcazo zepollether ukuba zithengwe ngokusekwe kwiimfuno zemveliso kunye neemfuno zokwenyani.
Nxibelelana nomthengisi kwaye ufumane ikowuti
Emva kokukhetha umthengisi ofanelekileyo, nxibelelana nabo ngefowuni, i-imeyile, okanye amaqonga kwi-Intanethi ukucela ulwazi oluneenkcukacha kunye namaxabiso ePolyet.
Thelekisa iikowuteshini kunye neenkonzo
Emva kokufumana iikowuti ezivela kubathengisi abaninzi, thelekisa amaxabiso kunye neenkonzo ezibonelelwa ngabathengisi abahlukeneyo ukuba bathathe isigqibo sokuba yeyiphi enokuhlangabezana neemfuno zakho zokuthengwa kwempahla nezinto zokuthenga.
Sayina ikhontrakthi yokuthenga
Emva kokugqibezela umthengisi, ikhontrakthi yokuthenga kufuneka isayinwe ukuba iqinisekise amalungelo kunye nezibonelelo zawo omabini amaqela.
Intlawulo kunye nokuHanjiswa
Emva kokutyikitya ikhontrakthi yokuthenga, yenza intlawulo ngokomgangatho ovunyelweyo. Nje ukuba umthengisi afumane intlawulo, baya kulungiselela ukuthunyelwa kwePolytere.
Ngesishwankathelo, ukuthengaPolyether Polyol (PPG)Ifuna umgudu kunye nexesha, kodwa okoko nje ufumana umthengisi ofanelekileyo, unokuqinisekisa umgangatho wemveliso kunye nokusebenza. Ukongeza, ukuthathelwa ingqalelo ngononophelo kufuneka kunikwe ekukhetheni umthengisi kunye namalungiselelo entlawulo ukuqinisekisa inkqubo yokuthenga engenamngcipheko nengafakwanga.
