Ukusabela Kwamakhemikhali Basisekelo Ngesikhathi Sokuvinjwa Selventless

Ngokuthuthuka okuqhubekayo kobuchwepheshe, ukugcwala kwe-sollentless kwamukelwa iningi labakhiqizi bephakethe eliguquguqukayo.

Ngokushesha, kulula, kube lula ukuthakazelisa imvelo, kungabizi kakhulu amathuba ezinzuzo zokumangalisa kwe-solventless.

Kubaluleke kakhulu kithi sazi ukusabela kwamakhemikhali okuyisisekelo ngesikhathi sokuvinjwa kwe-sollentless ukuze kukhiqizwe isisindo esingcono.

Isakhi ezimbiliUkunamathela kwe-solvenlessyenziwa yi-polyurethane (pu), uPu), uPu) ahlanganiswa yi-isocyanate (-NCO) ebizwa ngokuthi yingxenye, ne-polyol (-OH) ebizwa kakhulu yingxenye yeB. Imininingwane yokuphendula sicela uhlole ngezansi;

Ukusabela okuyisisekelo kuphakathi kuka-A no-B, i-anco inakho ukusabela kwamakhemikhali nge -Oh, ngasikhathi sinye, ngenxa yamanzi ibuye ibe neqembu le-chemic, amanzi azoba nokusabela kwamakhemikhali nge-commen₂, Isikhutha. Ne-polyurea.

I-CO₂ Kungadala ukuthi inkinga bubble ne-polyurea kungadala uphawu lokulwa nokushisa. Ngaphandle kwalokho umswakama uphakeme ngokwanele, amanzi azodla okuningi kakhulu kwengxenye. Umphumela wokuthi ukunamathela kungakwazi ukwelashwa ama-100% futhi amandla eBonding azokwehla.

Ngamafuphi, siphakamisa ukuthi;

Isitoreji sokunamathela kufanele sigcinwe endaweni epholile, eyomile kude nomswakama

I-workshop kufanele igcine umswakama phakathi kwama-30% ~ 70%, bese usebenzisa i-AC ukulawula inani lomswakama.

Ngaphezulu ukusabela okuyisisekelo kwamakhemikhali phakathi kwezikhangiso ezimbili ezihlanganisiwe, kepha ukunamathela kwe-mono-contensive kuzohluka ngokuphelele, sizokwethula ukusabela kwamakhemikhali kwe-mono ngokuzayo.
