Thenga i-Hot Maleated Rosin eyenziwe e-China. I-Harvest Enterprise ingumkhiqizi we-Maleated Rosin kanye nomphakeli e-China.
1.Ngoyinki wokuphrinta we-offset (i-phenol mahhala)
2.Ngoyinki be-Gravure(iphakethe lebhokisi)
3.Ngeziyinki ezisekelwe etshwaleni
4.Okunamathelayo
5.Ngopende Wokumaka Emgwaqeni
I-Harvest Enterprise ingumkhiqizi ohamba phambili wase-China we-Maleated Rosin, umhlinzeki kanye nomkhiqizi. Ukunamathela ekuphishekeleni ikhwalithi ephelele yemikhiqizo, ukuze i-Maleated Rosin yethu yaneliswe amakhasimende amaningi.
Izici
I-Maleated Rosin, eyaziwa nangokuthi i-fuma rosin, ikhiqizwa ngokuyinhloko i-rosin, i-unsaturated polyacids ngochungechunge lwezinqubo ze-polymerization, ukuqiniswa kanye ne-decolorization. Inezinga eliphezulu lokuncibilika, ukuzinza okuhle kwamanzi, ukuncibilika kalula ku-ester, utshwala, i-alcohol ether kanye namanzi e-amine. I-Maleated Rosin iyasebenza ekuthuthukiseni umbala we-pigment, isicwebezelisi nokuhlakazeka lapho isetshenziswa kombala.
Isicelo
I-Maleated Rosin ne-Fumarated Rosin zisetshenziswa kabanzi embonini elandelayo.
1. Imboni kapende
Kuyimpahla eluhlaza embonini kapende futhi isetshenziswa kakhulu ekukhiqizeni ama-desiccants, izithambisa namafutha okomisa okwenziwa. I-resin efana ne-rosin ihlangana ne-calcium oxide ekugcineni yakhe i-rosin ebaliwe, esetshenziselwa ukuthuthukisa ubulukhuni nokumelana namanzi kwefilimu kapende embonini yokumboza. I-rosin ingenza umbala wepende ucace kakhulu, wome ngokushesha, futhi ifilimu kapende ibushelelezi futhi akulula ukuwa.
2. Imboni yensipho
Kubiliswe nge-caustic soda ukwenza insipho ye-rosin. Inezici zokuthamba, ikhono eliqinile lokulwa nokungcola, ukuncibilika kalula emanzini, kulula ukwenza igwebu futhi kulula ukuncibilika emafutheni. Ngakho-ke, i-rosin resin isetshenziswa kabanzi embonini yensipho.
3. Imboni yamaphepha
Ngokuvamile, isetshenziselwa inqubo ye-gluing yephepha. I-inki ingena kalula ephepheni lethishu futhi ayihlakazi kangcono i-varnish. Ngokuvamile, embonini yephepha, ama-rosin resin amukelekile asuka ebangeni le-Leval N kuya ku-F. Njengoba iphepha linamabanga nezigaba ezahlukene, inani lihlukile. Ngokujwayelekile, inani elijwayelekile liyi-10 kg ye-rosin toni ngalinye lephepha.

Ukuphepha Kokuphepha
Gqoka amagilavu, izibuko zokuphepha nezicathulo zokuphepha lapho usebenzisa. Uma kwenzeka uthintana neso, lishaye ngokushesha; uma kwenzeka uthinta isikhumba, sihlanze.

Ukuphatha
Ukuphatha: Gcina kude nomlilo kanye nomthombo wokushisa. Ukubhema kwenqatshelwe ngokuphelele emsebenzini. Ilayishwe kancane futhi ikhipha kancane. Indawo yokusebenza kufanele ilungise izinto zokucisha umlilo.
Isitoreji: Kufanele sigcinwe endaweni epholile engenamoya, kude noMlilo, kude nomthombo wokushisa. Akuvumelekile ukusebenzisa ithuluzi noma okokusebenza okulula ukukuhlasimulisa.
