Iphasi loke - I-PVC Paste Resin: I-Polymer ekhethekileko yokusetjenziswa okuhlukahlukeneko
Iimfanelo eziphathekako nezamakhemikhali
Ukubukeka nokunzinza: Ebujameni bayo obujayelekileko, i-PVC Paste Resin ivela njenge-paste ebushelelezi, efanako enobunjalo obukhilimu. Ubukhulu bezinhlayiya ze-PVC e-paste buncani khulu, kanengi buphakathi kwama-0.1 ukuya ku-2 microns, okwenza bona igeleze kuhle khulu nekghono lokusetjenziswa lula nofana ukubunjwa ibe ziindlela ezihlukahlukeneko.
Ukuthamba: Ukuqina kwe-PVC Paste Resin kungalungiswa ngokunembileko ngokutjhugulula umhlobo nenani leplastiki esetjenzisiweko, kanye nezinye izinto ezingezelelweko. Iinhluthu ezine-viscosity ephasi zilungele ukusetjenziswa okutlhoga ukugeleza okukhulu, njengokubunjwa ngokutjhinga, lokha iinhluthu ezine-viscosity ephezulu zilungele iinkambo ezifana nokubunjwa kwe-slush nofana ukuphosa.
Ukuziphatha kweplastiki: Lokha nayifuthumeleko, iplastiki ese-PVC Paste Resin ingena ngaphakathi eenhlayiya ze-PVC, okwenza bona zivuvuke begodu zihlangane ndawonye, okurholela ekutheni kube nomkhiqizo oqinileko, otjhugulukako, nofana oqinileko ngokuya ngokwakheka. Ikambiso yokwenza iplastiki iyabuyiselwa emuva ngezinga elithileko, ivumela ukusetjenziswa kabutjha nangabe kuyatlhogeka.
Ukuzinza kwamakhemikhali: Njengeminye imikhiqizo ye-PVC, i-PVC Paste Resin itjengisa ukujamelana okuhle namakhemikhali ahlukahlukeneko, kufaka hlangana ama-esidi, ama-alkali, kanye nama-solvent amanengi. Kodwana, ukujamelana kwayo namakhemikhali kungathuthukiswa namkha kutjhugululwe ngokungezelelwa kwezinto ezithileko eziqinileko nezingezelelweko.
Iindawo zokufaka isibawo
Ukugcoba nokusetjenziswa kokugcoba: Isetjenziselwa ukuvala izinto ezihlukahlukeneko ezifana neensimbi, iinkuni, kanye nezindwangu. Ebubulweni leenkoloyi, isetjenziswa ematjhasini weenkoloyi kanye neengcenye ezingaphasi komzimba ukunikela ngokuvikeleka ekugqwaleni nokuvikela umdumo. Ifenitjhara nezinto zokusebenza, i-PVC Paste Resin - ukugqoka okusekelwe kukunikela ukuqeda okuqinileko, okuhle okujamelana nokuklwebheka namabala.
Ukukhiqizwa kwamathoyizi: Into ekhethwako ekukhiqizeni amathoyizi ngebanga lokuphepha kwayo, ukutjhuguluka, nobulula bokubumba. Ingasetjenziselwa ukwenza amathoyizi athambileko, imifanekiso yezenzo, nezinye izinto zokudlala ezineemfanelo ezinemininingwana nemibala ekhanyako. Ubukhulu bezinhlayiya ezincani ze-resin buqinisekisa ukuqeda okubushelelezi, okwenza bona amathoyizi aphephile kobana abantwana baphathe.
Ibubulo leencathulo: Ifakwe ekukhiqizeni amasole wezicathulo, ama-uppers, nezinye izinto. Iinsetjenziswa zezicathulo ezisekelwe ku-PVC Paste Resin zaziwa ngokuguquguquka kwazo, ukuqina, nokujamelana nokuguga nokudabuka. Zingalungiswa lula ukuhlangabezana neemfuneko ezihlukahlukeneko zokuklama, zinikela ngemibala ehlukileko nokuthungwa.
Iinsetjenziswa zezokwelapha: Isetjenziselwa ukwenza ezinye iinsetjenziswa zezokwelapha, ezifana namagilavu alahlwako, amakhafu wokugandeleleka kweengazi, kanye neminye imihlobo yamatjhubhu. Ukuvumelana kwayo kwezinto eziphilako kungathuthukiswa ngokwakhiwa nokusetjenziswa okufaneleko, ukuqinisekisa bona ihlangabezana namazinga aqinileko wokuphepha nokuhlanzeka atlhogekako emkhakheni wezokwelapha.
Iindlela zokuzilungiselela
I-Emulsion Polymerization: Le ngenye yeendlela ezijayelekileko zokukhiqiza i-PVC Paste Resin. Ama-monomers we-vinyl chloride ahlakazwa emanzini kanye nama-emulsifiers nama-initiators. Iinhlayiya ze-polymer eziphumelako zincani begodu zifana, okusizako ekuzuzeni ukuvumelana okubushelelezi. Ngemva kokuhlanganiswa, i-emulsion ivamise ukusetjenzwa ukususa i-emulsifier nezinye izinto ezingcolileko, bese ihlanganiswa namaplastiki nezinye izinto ezingezelelweko ukwakha i-resin yokugcina.
Ukubunjwa okukhulu: Ekambisweni yokwenza amapholimera amanengi, ama-monomers we-vinyl chloride ahlanganiswa ngaphandle kwesisombululo, okuphumela emkhiqizweni we-PVC ohlanzekileko. I-polymer leyo iyasilwa ibe ziinhlayiya ezincani bese ihlanganiswa namaplastiki nezinye izinto ukwenza i-resin ye-paste. Indlela le ingakhiqiza i-PVC Paste Resin eneempawu ezihle khulu, kodwana itlhoga imitjhini yokucubungula eyinkimbinkimbi nokulawulwa kwenqubo okuqinileko.
Ukumiswa kwe-Polymerization Modified: Abanye abakhiqizi basebenzisa ikambiso yokumiswa okutjhugululiweko ukukhiqiza i-PVC Paste Resin. Ngokulungisa ubujamo be-polymerization kanye nomhlobo wama-ejenti wokulengisa, bangakwazi ukulawula ubukhulu bezinhlayiya nobujamo bezinhlayiya ze-PVC ukuthola izakhiwo ezifunwako zokunamathisela. Indlela le inikela ngokulinganisela hlangana nekhwalithi yomkhiqizo kanye neendleko zokukhiqiza.
Iinqabo
Ubujamo bokubulunga: I-PVC Paste Resin kufanele igcinwe endaweni epholileko, eyomileko kude nelanga nemithombo yomtjhiso. Ukuvezwa emazingeni womtjhiso aphezulu kungenza bona ipulasitiki iphume namkha i-resin ibe yiplastiki ngaphambi kwesikhathi, okuthinta ikhwalithi nokusebenza kwayo. Kuqakathekile nokuthi iinsetjenziswa zokulondoloza zivalwe kuhle ukukhandela ukungena komswakama nomoya, okungadosela ekutheni i-resin yehle.
Ukuphepha kokuphatha: Ngesikhathi sokuphatha, kufanele kuqashelwe ukugwema ukuthintana nesikhumba namehlo. Iinthako zeplastiki nezinye izinto ezingezelelweko ku-resin ye-paste zingabanga ukucasuka kwesikhumba nofana ukusabela kokungavumelani kwabanye abantu. Abasebenzi kufanele bagqoke izinto zokuzivikela ezifaneleko, ezifana namagilavu namagilasi wokuvikela. Nakwenzeka ukuthintana ngengozi, indawo ethintekako kufanele ihlanzwe msinyana ngamanzi amanengi, begodu kufanele kufunwe isizo lezokwelapha nangabe kuyatlhogeka.
Ukucabangela Ukucubungula: Lokha nakusetjenziswa i-PVC Paste Resin, ukulawula izinga lokutjhisa elifaneleko kuqakathekile. Ukutjhisa khulu kungadosela ekuboleni kwe-PVC begodu kukhutjhwe amagesi ayingozi, afana ne-hydrogen chloride. Kufanele kube nokungena komoya okwaneleko endaweni yokusebenza ukuqinisekisa ukuphepha kwabasebenzi nokukhandela ukubuthelelana kwentuthu enobuthi. Phezu kwalokho, ukusetjenziswa kwezinto eziqinileko ezifaneleko kanye neensizakusebenza kungasiza ekwenzeni ngcono ukuzinza kokutjhisa nokusebenza kwe-resin yokunamathisela.
