Mu myaka yashize, ifu nyinshi ya resin reberi, ifu yimbaraga zidashobora kwihanganira amazi nandi mafu ya reberi ihendutse cyane yagaragaye kumasoko kugirango isimbuze emulioni gakondo ya VAE (vinyl acetate-ethylene copolymer), yatewe kandi yumye kandi ikozwe mu ifu ya rubber.Ifu ya latx yatatanye, none ni irihe tandukaniro riri hagati yifu ya resin na redispersible powderx, ifu ya resin ishobora gusimbuza ifu ya redxersible powder?
Gerageza muri make itandukaniro riri hagati yibi byombi:
01. Isubirwamo rya poro ya latex
Kugeza ubu, ifu ya redispersible latex ikoreshwa cyane kwisi ni: vinyl acetate na Ethylene copolymer ifu (VAC / E), Ethylene, vinyl chloride na vinyl laurate ternary copolymer ifu (E / VC / VL), acide acetike Vinyl ester, Ethylene hamwe na aside irike cyane ya vinyl ester ternary copolymer ifu (VAC / E / VeoVa), izi fu eshatu zisubirwamo za latx ziganje kumasoko yose, cyane cyane vinyl acetate na powder etolyne copolymer ifu VAC / EE, ifata umwanya wambere murwego rwisi kandi ihagarariye tekiniki ibiranga ifu ya polymer isubirwamo.Haracyari igisubizo cyiza cya tekiniki mubijyanye nuburambe bwa tekinike hamwe na polymers ikoreshwa muguhindura minisiteri:
1. Nimwe muma polymers akoreshwa kwisi;
2. Uburambe bwo gusaba mubijyanye nubwubatsi nibyinshi;
3. Irashobora kuzuza imiterere ya rheologiya isabwa na minisiteri (ni ukuvuga kubaka byubatswe);
4. Polymer resin hamwe nabandi ba monomers ifite ibiranga ibintu bihindagurika bihindagurika (VOC) na gaze nkeya;
5. Ifite ibiranga UV nziza cyane, irwanya ubushyuhe bwiza nigihe kirekire;
6. Kurwanya cyane saponification;
7. Ifite uburebure bwagutse bwikirahure (Tg);
8. Ifite uburyo bwiza cyane bwo guhuza, guhuza n'imiterere;
9. Kugira uburambe burebure mubikorwa byo gutunganya imiti yuburyo bwo gutanga ibicuruzwa byiza kandi bifite uburambe mukubungabunga ububiko;
10. Biroroshye cyane guhuza hamwe na colloid ikingira (polyvinyl alcool) hamwe nibikorwa byinshi.
02. Ifu ya resin
Ibyinshi mu ifu ya "resin" ya reberi ku isoko irimo imiti ya DBP.Urashobora kugenzura ububi bwibi bintu byimiti, bigira ingaruka kumikorere yabagabo.Umubare munini wubwoko bwa reberi yegeranijwe mububiko no muri laboratoire, kandi ifite ihindagurika runaka.Isoko rya Beijing, rizwi cyane kubera ubwinshi bw '"ifu ya rubber", ubu rifite amazina atandukanye y "ifu ya rubber" yashizwe mumashanyarazi: ifu yimbaraga zidashobora kwihanganira amazi, ifu ya reberi, nibindi biranga:
1. Gukwirakwiza nabi, bamwe bumva batose, bamwe bumva flocculent (bigomba kuba ibintu byoroshye nka sepiolite) kandi bimwe byera kandi byumye gato ariko biracyahumura nabi;
2. Impumuro nziza cyane;
3. Amabara amwe yongeyeho, kandi amabara agaragara ubu ni umweru, umuhondo, imvi, umukara, umutuku, nibindi.;
4. Umubare winyongera ni muto cyane, kandi ingano yinyongera kuri toni imwe ni 5-12 kg;
5. Imbaraga zo hambere nibyiza bitangaje.Isima nta mbaraga ifite muminsi itatu, kandi ikibaho gishobora kubora no kugumya;
6. Bavuga ko ubuyobozi bwa XPS budakeneye umukozi wa interineti;
Binyuze mu ngero zabonetse kugeza ubu, dushobora kwanzura ko ari resin ishingiye kumashanyarazi yamamajwe nibikoresho byoroshye, ariko uyitanga arashaka kwirinda nkana ijambo "solvent", bityo ryitwa "ifu ya rubber".
ibitagenda neza:
1. Kurwanya ikirere cyumuti nikibazo gikomeye.Ku zuba, bizashira mu gihe gito.Nubwo yaba atari ku zuba, guhuza imiyoboro bizabora vuba kubera kubaka urwobo;
2. Kurwanya gusaza, ibishishwa ntabwo birwanya ubushyuhe, buriwese arabizi;
3. Kubera ko uburyo bwo guhuza ari ugusenya intera yinama yububiko, kurundi ruhande, nayo isenya intera ihuza.Niba hari ikibazo cyiki kibazo mugice cyanyuma, ingaruka zizica;
4. Nta ntangarugero yo gusaba mubihugu byamahanga.Hamwe nuburambe bwibanze bwimiti ikuze mumahanga, ntibishoboka kutavumbura ibi bikoresho.
Ifu ya redxersible latex
1. Igicuruzwa cya pisitori ya redxersible latx ni ifu yumuti wogusubirana ifu, ikaba kopolymer ya Ethylene na vinyl acetate, hamwe na alcool ya polyvinyl nka colloid ikingira.
2. Ifu ya VAE isubirana ifu ya latx ifite imiterere yo gukora firime, 50% yumuti wamazi ukora emulion, kandi ikora firime imeze nka plastike nyuma yo gushyirwa mubirahuri amasaha 24.
3. Filime yakozwe ifite imiterere ihindagurika kandi irwanya amazi.Irashobora kugera ku rwego rwigihugu.
4. Redispersible latex ifu ifite imikorere ihanitse: ifite ubushobozi bwo guhuza cyane, imikorere idasanzwe nigikorwa cyindashyikirwa cyamazi kitagira amazi, imbaraga nziza zo guhuza, itanga minisiteri hamwe na alkali nziza cyane, kandi irashobora kunoza imbaraga zifatika za minisiteri Usibye plastike, kwambara birwanya n'ubwubatsi, ifite ihinduka rikomeye muri anti-crack.
ifu ya resin
1. Ifu ya reberi ya reberi ni ubwoko bushya bwo guhindura ibicuruzwa nka reberi, resin, polymer ndende, hamwe nifu ya rubber nziza;
2. Ifu ya resin ya rubber ifite uburebure muri rusange, kwambara nabi, gutatanya nabi, bamwe bumva flocculent (igomba kuba ibintu byoroshye nka sepiolite), kandi hariho ifu yera (ariko ifite impumuro mbi isa na kerosene);
3. Ifu imwe ya resin irashobora kwangirika kurubaho, kandi kwirinda amazi ntabwo ari byiza.
4. Kurwanya ikirere no kurwanya amazi yifu ya resin reberi biri munsi yifu ya latex.Kurwanya ikirere nikibazo gikomeye.Ku zuba, bizashira mu gihe gito.Nubwo yaba itari mwizuba, guhuza imiyoboro bizaterwa nubwubatsi bwa cavit, bizanabora vuba;
5. Ifu ya reberi ya rubber ntabwo ifite ububobere, kereka niba ihinduka.Ukurikije ibipimo ngenderwaho byo gupima urukuta rwo hanze, gusa ibyangiritse byubuyobozi bwa polystirene byujuje ubuziranenge.Ibindi bipimo ntabwo bigera kubisanzwe;
6. Ifu ya reberi irashobora gukoreshwa gusa muguhuza imbaho za polystirene, ntabwo ari amasaro ya vitrifatique hamwe nimbaho zidafite umuriro.
