Lo mkhiqizo i-adhesive encibilikayo emanzini, okuyi-adhesive thermoplastic elungiselelwe i-polymerization ye-vinyl acetate monomer ngaphansi kwesenzo se-initiator.Ngokuvamile ibizwa ngokuthi i-latex emhlophe noma i-emulsion ye-PVAC ngamafuphi.Igama layo lamakhemikhali i-polyvinyl acetate adhesive.Yenziwe nge-acetic acid ne-ethylene ukuze kuhlanganiswe i-vinyl acetate ene-titanium dioxide eyengeziwe (amabanga aphansi engezwa nge-calcium ekhanyayo, i-talc, nezinye izimpushana).Bese benziwa i-polymerized nge-emulsion.Njengoketshezi olujiyile olumhlophe olumhlophe.
Ukomisa ngokushesha, ukuthambekela okuhle kokuqala, ukusebenza kahle;ukunamathela okuqinile, amandla aphezulu okucindezela;ukumelana nokushisa okuqinile.
ukusebenza
(1) I-latex emhlophe inochungechunge lwezinzuzo ezifana nokuphulukiswa kwezinga lokushisa elivamile, ukuphulukiswa ngokushesha, amandla okubopha aphakeme, futhi isendlalelo sokubopha sinokuqina okungcono nokuqina futhi akulula ukuguga.Ingasetshenziswa kabanzi ekuhlanganiseni imikhiqizo yephepha (i-wallpaper), futhi ingasetshenziswa njenge-adhesive yezingubo ezivikela amanzi kanye nezinkuni.
(2) Isebenzisa amanzi njengesisabalalisi, iphephile ukusetshenziswa, ayinabo ubuthi, ayinakushi, kulula ukuyihlanza, iqina endaweni yokushisa yasekamelweni, inamathela kahle okhunini, ephepheni nasendwangu, inamandla okubopha okuphezulu, futhi iselaphekile. ungqimba olunamathelayo alunambala Lusobala, ukuqina okuhle, alungcolisi into eboshiwe.
(3) Ingasetshenziswa futhi njengesilungisi se-phenolic resin, i-urea-formaldehyde resin nezinye izinto zokunamathisela, futhi isetshenziselwe ukwenza upende we-latex we-polyvinyl acetate.
(4) I-emulsion inokuzinza okuhle, futhi isikhathi sokugcina singafinyelela ngaphezu kwesigamu sonyaka.Ngakho-ke, ingasetshenziswa kabanzi ekunyatheliseni nasekubopheni, ekwenzeni ifenisha, nasekuhlanganiseni iphepha, izinkuni, indwangu, isikhumba, izitsha zobumba, njll.
Izici
1. Inokunamathela okuqinile ezintweni ezinama-porous ezifana nokhuni, iphepha, ukotini, isikhumba, izitsha zobumba, njll., futhi i-viscosity yokuqala iphakeme kakhulu.
2. Ingelapheka ekamelweni lokushisa, futhi isivinini sokuphulukisa siyashesha.
3. Ifilimu isobala, ayingcolisi ukunamathela, futhi kulula ukuyicubungula.
4. Ukusebenzisa amanzi njengendawo yokuwahlakaza, awashi, awanayo igesi enobuthi, ayingcolisi imvelo, futhi aphephile futhi awangcolisi.
5. Iwuketshezi lwe-viscous oluyingxenye eyodwa, olusebenziseka kalula.
6. Ifilimu eselashiwe inezinga elithile lokuqina, ukumelana nokuhlanjululwa kwe-alkali, i-asidi ehlanjululwe, kanye nokumelana nowoyela.
Isetshenziselwa ikakhulukazi ukucubungula izinkuni, ukuhlanganiswa kwefenisha, imibhobho kagwayi, umhlobiso wokwakha, ukubopha indwangu, ukucubungula umkhiqizo, ukuphrinta nokubopha, ukukhiqizwa kwezandla, ukucubungula isikhumba, ukulungisa amalebula, ukunamathela kwamathayili, njll. I-Agent enamathela evumelana nemvelo.
amandla
I-latex emhlophe enobungani bemvelo kufanele iqale ibe namandla anele okubopha, ukuze kuqinisekiswe ukuthi ikhwalithi yemikhiqizo yephepha ngeke iphazamiseke ngemva kokubopha.
Ukuze wahlulele ukuthi amandla okubopha we-latex emhlophe evumelana nemvelo afanelekile, izingcezu ezimbili zezinto ezinamathele zingadatshulwa ngokuhambisana nesixhumi esibonakalayo sokubopha.Uma izinto eziboshiwe zitholakala zonakaliswe ngemva kokudabula, amandla okubopha anele;uma kuphela isixhumi esibonakalayo sokubopha sihlukanisiwe, Kubonisa ukuthi amandla e-latex emhlophe evumelana nemvelo awanele.Kwesinye isikhathi i-latex emhlophe evumela imvelo engasebenzi kahle izosuswa futhi ifilimu izoba brittle ngemva kokugcinwa isikhathi esithile endaweni enezinga lokushisa eliphezulu noma izinga lokushisa eliphansi.Ngakho-ke, kuyadingeka ukwenza ukuguquka kwezinga lokushisa eliphezulu kanye nokuhlolwa kokushisa okuphansi kwe-embrittlement ukuze kutholakale ukuthi ikhwalithi yayo inokwethenjelwa yini.
