Njengamanje, imakethe ye-PO yasekhaya ivaliwe ukuhweba nokutshalwa kwezimali okumbalwa emakethe.Ukuze uthole impahla eluhlaza, i-propylene ibuthakathaka futhi iqhuma, i-chlorine isebenza ngokujwayelekile.Ngakho izindleko zendlela ye-chlorohydrin zizozinza ngokuguquguquka okuncane.

Uma kukhulunywa ngabahlinzeki, iJinling yehlise umthamo wayo wafinyelela ku-70% isuka kuma-24^thfuthi i-Huatai yamisa indawo yayo kusukela ngo-25^th.Ngakho-ke, ukunikezwa kuzoncipha ngokusobala.Izosekela izindleko ze-PO.

Kodwa-ke ama-oda e-polyether polyol ne-polymer polyol awalungile ngokwanele, ngisho nezitshalo eziningi ezithengwe ngesonto eledlule.Njengamanje, bambalwa abathengi abafaka ama-oda abo ngaphandle kwalabo okufanele bakwenze.Ngaphandle kwalokho, izinto zokuhamba azibusheleli njengakuqala ngenxa ye-sanitary everts.Imakethe ihlanganiswe okwesikhashana.Sidinga ukunaka kakhulu ukunikezwa kwezinto ezingavuthiwe futhi sibone ukuthi kuzokwenzekani ngaleso sikhathi.

Isimemezelo:Okunye okuqukethwe/izithombe kulesi sihloko zivela ku-inthanethi, futhi umthombo (okusuka ku-chem365) uqashelwe.Zisetshenziselwa kuphela ukukhombisa amaqiniso noma imibono eshiwo kulesi sihloko.Ezokuxhumana nokufunda kuphela, futhi akuzona ezinye izinjongo zezohwebo.Uma kukhona ukwephulwa komthetho, sicela usithinte ukuze sikususe ngokushesha.
