Uphononongo malunga noLungiso lwePolyurethane yasemanzini yokuGqiba koMfanekiso obonakalayo

Uphononongo kuLungiso loKugqitywa kwesikhumba sePolyurethane eManzi

Inkcazelo emfutshane:

Kwinkqubo yokuveliswa kwesikhumba, ukugqiba yinkqubo ebaluleke kakhulu, enempembelelo ebaluleke kakhulu kwixabiso lokusetyenziswa kwesikhumba.Ngophuhliso loqoqosho kunye nokuphuculwa okuqhubekayo kwemigangatho yokuphila kwabantu, abantu banemfuno eziphezulu kunye eziphezulu kwii-agent zokugqiba isikhumba, kwaye kwiminyaka yamuva nje, baye basondela ngokuthe ngcembe kuhlobo oluhambelana nokusingqongileyo.I-agent ye-polyurethane yokugqiba isikhumba samanzi inokuphepha ngokufanelekileyo ungcoliseko kunye netyhefu ye-agent yendabuko yokugqiba, kwaye ineempawu zokugcinwa lula, ukuthutha kunye nokungatsha.Inomsebenzi ogqwesileyo, kodwa isenayo impazamo ethile ekuxhathiseni ukunxiba kunye nokumelana namanzi.Ifuna abasebenzi abafanelekileyo ukuba baphonononge ngenkuthalo kwaye balungise iarhente yokugqibezela ufele lwe-polyurethane emanzini.

Ukuguqulwa kweAgent yokuGqiba ngesikhumba sePolyurethane emanzini

Khetha i-10g ye-attapulgite yodongwe, yongeza i-100ml ye-hydrochloric acid kunye ne-concentration ye-1mol / L kudongwe, xuba ezimbini, udibanise iiyure ezingama-24, uze uzipholise.Emva koko, i-filtrate ihlanjwe ngamanzi adibeneyo ukuze i-filtrate ingabi nayo i-ion chloride.I-filtrate yomiswa kwi-oven kunye nokushisa kwe-100 ° C. emva kokulinda iiyure ezingama-24, igalelwe ibe ngumgubo.Ngaloo ndlela, i-attapulgite ephathwa nge-asidi ifunyenwe.

Ukuguqulwa kweLotion ye-Polyurethane Resin yaseManzi nge-Attapulgite

Lungiselela i-asidi ephathwe i-attapulgite ibe yi-dispersion kunye neqhekeza elikhulu le-10%, sebenzisa i-electromagnetic ukuvuselela iiyure ezimbini, emva koko uqhube i-ultrasonic dispersion iyure enye.Emva koko, yongeza i-aqueous polyurethane resin lotion kwi-dispersion phantsi kweemeko ezivuselelayo, apho iqhekeza elikhulu le-aqueous polyurethane resin lotion yi-20%, Umxholo we-asidi ephathwayo ye-attapulgite ilawulwa ukuba ibe phakathi kwe-0.1% kunye ne-5% ye-polyurethane yamanzi. i-resin lotion, ezimbini zivumelekile ukuba ziphendule kwi-70 ℃ iiyure ezine, kwaye ke imveliso igxininiswe malunga ne-20% ngokusebenzisa i-evaporator ejikelezayo.Ngaloo ndlela, ukuguqulwa kwe-polyurethane resin lotion yamanzi ngokusebenzisa udongwe lwe-attapulgite kuqalwa.Emva koko, ifilimu yenziwe ngokusetyenziswa kwemveliso elungisiweyo, kwaye i-20g yemveliso yafakwa kwi-mold ye-polytetrafluoroethylene ukufezekisa ukwenza ifilimu.
