Umphumela we-ejenti elwa namanzi ezinhlakalweni zokuhlanganisa kanye nephepha elihlanganisiwe

Ngokuthuthuka okusheshayo kwemboni yamaphepha, ikakhulukazi iphepha elihlanganisiwe lithuthukisiwe ngokushesha, imboni yokuphrinta kwizidingo zekhwalithi yephepha ehlanganisiwe iya ngokuya iphakeme. Ukuze uqinisekise ikhwalithi yokuphrinta, ingaphezulu lephepha elihlanganisiwe kumele libe nekhono lokumelana nengxabano emanzi. Ukumelana nokushayisana okumanzi kubhekisele ezingeni lomonakalo ebusweni bephepha ngemuva kwendawo ethile yephepha nekhadibhodi kufakwa ngaphansi kwengcindezi emanzi ngaphansi kwengcindezi ethile, ekhombisa amandla angaphansi kwephepha .

Kanye nephepha elihlanganisiwe elinamanzi elinezidingo ezikhethekile, ukuze likwenze lithole amandla okumelana namanzi okuvimbela amanzi kanye namanzi, enqubweni yokukhiqiza amaphepha, ngaphezu kwenqubo yokulinganisa kumenzeli we-ugent kanye ne-ejenti esheshayo Ukwengeza izengezo zokumelana kwamanzi kwinqubo yokulungiselela ukuhlanganisa, ukuze ungqimba lokuthola imali ukuze uthole ukusebenza okuhle kwamanzi.

Ngasikhathi sinye, ngokususelwa ekucabangeni kokuphepha nokuvikelwa kwezemvelo, izidingo zekhwalithi kazwelonke zokugoqa iphepha kanye nephepha lasekhaya ziqala ngokwengeziwe, futhi manje sekuyindlela yokusebenzisa amanzi e-polyomide polyurea. IPapu isetshenziswa kabanzi, ngoba ayiqukethe mahhala i-formaldehyde, futhi iyashesha, isebenza uma iphuma emshinini, futhi ingathuthukisa ngempumelelo ukuguquguquka kwephepha elihlanganisiwe kwinqubo yokuphrinta.

I-PAPU inesicelo esiqinile evezweni ye-PH, kanye nokubonakala kwePapu okungezwe kupende kuzinzile futhi ijubane lokuphulukisa liyashesha. I-Papu Molecular chain iqukethe iqembu le-chloroethanol neqembu lama-polyamine amaqembu amabili asebenzayo, okuyiqembu le-chloroethanol kanye ne-wite adhesive khiqiza i-chemic bonding bond, i-pollamine geyimu yokuhlobisa ukuze wakhe inethiwekhi yefilimu yokulapha, okuyinto Umthombo oyinhloko wokumelana kwamanzi ePapu, kodwa futhi njengemigomo yokusebenzisana yamanzi ekhuthazayo.

Ekusetshenzisweni kwangempela, i-papu ayikwazi nje kuphela ukuthi kwakha amabhondi amakhemikhali ngesitashi esihlanganisiwe, kepha futhi akha ama-Ionic Bonds nge-styrene butadiene latex, futhi ukumelana nokuphazamiseka okumanzi kwenhlanganisela kuyanda. Ngaphezu kwalokho, izakhiwo ezibuthakathaka ze-cationic ze-papu amelana namanzi amelana nazo zingakhiqiza i-micro-floccution nge-anings in the coating, ngcono ukuqupha, ukuthuthukisa ukusebenza kwephepha lokuhlanganisa, futhi kuthuthukise ukusebenza kwephepha lokupholisa.

Impahla ye-Rheological iyinkomba ebalulekile yopende, i-Papu yohlobo lwamanzi amelana namanzi ingakhuphula i-viscosity yopende, engeza uhlobo lwe-papu amelana namanzi ngemuva kokuba inani lokulahleka kwamanzi lincishisiwe, ukugcinwa kwamanzi kungcono. Uhlobo lwePapu Uhlobo lwamanzi amelana namanzi lufanele ukulungiswa kokulungiswa okuphezulu kwepende, futhi ukusebenza kokugcinwa kwamanzi kungcono.
