Iindaba

Njengoko i-viscosity ye-resin esekwe emanzini iphantsi kakhulu, ayinakukwazi ukufikelela kwiimfuno zokusebenza nokusebenza kokudibana, ke kufuneka isebenzise i-tickener efanelekileyo ukuze ilungiswe i-vicketity ye-viscofity echanekileyo.

Zininzi iintlobo zeentlobo zeziqwengana. Xa ukhetha i-thiskers, ukongeza ekusebenzeni kwayo ngokukhululekileyo kunye nokulawulwa kwe-RHEOOLOL into yokuthambisa, ezinye izinto kufuneka zithathelwe ingqalelo ukwenza umsebenzi wokukhetha, eyona imbonakalo ilungileyo yokwakha.

Ukukhethwa kweentlobo-ntlobo ze-thi cokener ikakhulu kusekwe kwimfuno kunye neyona meko yokuqulunqa.

Xa ukhetha kwaye usebenzisa i-thiskers, ezi zinto zibalulekile.

I-1. Ubunzima obuninzi bemolekyuli bunenqanaba elikhulu lezinto ezithengiswayo xa kuthelekiswa nobunzima obuphantsi kwaye zibonise ukusebenza kakuhle ngexesha lokugcina. Kwaye xa inqanaba lamachibi liyanda, ilizwe elivuthiweyo litshatyalalisiwe, kokukhona umzila wechiza, iphantsi kwesiphumo sobunzima bemolekyuli kwi-vickosity. Le ndlela iqaqambileyo ayinanto yakwenza nezinto ezisezantsi, imibala kunye nokongezwa kwezinto ezisetyenzisiweyo, kufuneka kuphela ukukhetha ubunzima bemolekyuli efanelekileyo kwaye ilungelelanise i-ticker inokufumana i-ticker inokufumana i-vickosity elungileyo, kwaye ke isetyenzisiwe.

2.Unule munokener sisisombululo se-viol ye-viol kunye ne-diol okanye i-diol ether njenge-smolvent, ngomxholo oqinileyo wama-20% ~ 40%. Indima ye-slinvent ye-slitvent kukuncamathelisanga, kungenjalo thina i-thi chuzle kwizizwe zejeli ngexesha elifanayo. Kwangelo xesha, ubukho besinyibilikisi bunokuphembelela imveliso ukusuka kwi-freazing, kodwa kufuneka ifudumezwe ebusika ngaphambi kokusetyenziswa.

3. Iimveliso eziqinileyo eziphantsi, iimveliso ze-viscosity eziphantsi kulula ukulahla kwaye zinokuhanjiswa kwaye zigcinwe kwi-bulk. Ke ngoko, ezinye ii-heur zinomxholo oqinisekileyo wokubonelela ngemveliso efanayo. Umxholo wesinyibiliki we-viskwound ophantsi uphakamileyo, kwaye i-viscosity ye-Shear yepeyinti iya kuba isezantsi kakhulu xa isetyenziswa, enokuthi isetyenziselwe ukunciphisa i-CO-SLEDEP eyongeziweyo kwenye indawo.

4. Phantsi kweemeko ezifanelekileyo zokuxuba, i-hear ye-hear ye-vircovity inokongezwa ngokuthe ngqo kwipeyinti ye-Latex. Xa usebenzisa iimveliso ze-viscofity ephezulu, i-thi checker kufuneka ichithwe ngumxube wamanzi kunye ne-smolven ngaphambi kokuba yongezwe. Ukuba uyongeza amanzi ukuze uchithe i-tickener ngqo, iya kunciphisa uxinzelelo lwesoluth-mveliso kwimveliso, eya konyusa i-adhesion kwaye ibangele ukuba kuphakame.

5. Ukongeza i-tickener kwitanki yokuxuba kufuneka iqine kwaye icotha, kwaye kufuneka ibekwe ecaleni kwetanki yodonga. Isantya songezelelo akufuneki sikhawuleze kangangokuba i-thi chulener ihlala kumphezulu wolwelo, kodwa kufuneka itsalwe kwi-shaft efudumeleyo, kungenjalo i-thi chunga ayiyi kuxutywa kakhulu okanye iphindwe ngenxa yoxinzelelo lwasekhaya.

I-6. I-heur tickener yongezwa kwitanki yokuxuba ipeyinti emva kwezinye izinto zolwelo kwaye phambi kwe-emulsion, ukuze kuqinisekiswe uluhlu lweglosi.

I-7. I-hase enzothunga yongezwa ngokuthe ngqo kwipeyinti kwi-emulsion ekwenzeni iipeyinti ze-Emoulsion ngaphandle kwe-dilution yangaphambi kwexesha okanye ukungathathi cala. Inokongezwa njengecandelo lokugqibela kwiSigaba sokuxuba, kwiSigaba sokuSula kwiPigment, okanye njengenxalenye yokuqala ekuxubeni.

8. Kuba ukuhamba yi-hase emulsion ephezulu, emva kongeziweyo, ukuba kukho i-alkali kwipeyinti ye-emulsion, iya kukhuphisana nale alkali. Ke ngoko, kuyafuneka ukongeza i-eulsion ye-hase kancinci kwaye ngokuthe ngcembe, kwaye ishukumisa kakuhle, kungenjalo, iya kwenza ukungazinzi kwe-gegrafition okanye i-eulsion binder yendawo yokuhlala.

9. I-Alkali inokongezwa ngaphambi okanye emva kokuba iarhente yongezwa. Inzuzo yokongeza ngaphambili kukuqinisekisa ukuba akukho uzinzo lwendawo yokusasazwa kwe-pigment okanye i-emulsion binder iya kubangelwa yi-gickeling grabing alkali evela kumphezulu we-pigment okanye i-binder. Inzuzo yokongeza iAlkali emva koko kukuba amasuntswana amakhulu asasazeke kakuhle ngaphambi kokuba atshixeke okanye anyibilikiswe yi-alkali, echithiwe yi-alkali, ethintelayo ekuqulunqweni, ngokuxhomekeka kwenkqubo yokwenza, izixhobo kunye nenkqubo yokwenza. Eyona ndlela ikhuselekileyo kukususa i-hase tickener ngamanzi kuqala kwaye emva koko uyicaphula ngeAlkali ngaphambi kwexesha.

I-10. I-Hase Thickener iqala ukungcungcutheka kwi-6, kwaye ukusebenza kwempumelelo kwe-PH ye-7 ukuya kwi-8. , ngaloo ndlela kuqinisekisa ukuzinza kwe-vikosity.
