Mu myaka yashize, ifu ya resin polymer nyinshi, ifu ya polymer yihanganira amazi menshi hamwe nifu ya polymer ihendutse cyane yagaragaye kumasoko kugirango isimbure emulioni gakondo ya VAE (vinyl acetate-ethylene copolymer), yatewe kandi yumye kandi bikozwe mu ifu ya polymer. Ifu ya polymer yatatanye, none ni irihe tandukaniro riri hagati yifu ya resin nifu ya polymer isubirwamo, ifu ya resin ishobora gusimbuza ifu ya polymer idasubirwaho? Ikigo cy’ikoranabuhanga cya Mortar kizakuyobora gusesengura muri make itandukaniro riri hagati yibi byombi:
(1), ifu ya polymer isubirwamo
Kugeza ubu, ifu ya polymer isubirwamo ikoreshwa cyane ku isi ni: vinyl acetate na porojeri ya Ethylene (VAC / E), Ethylene, vinyl chloride na vinyl laurate ternary copolymer ifu (E / VC / VL), acide acetike Vinyl ester, Ethylene hamwe na aside irike ya vinyl ester ternary copolymer ifu (VAC / E / VeoVa), izi fu eshatu zisubirwamo polymer yiganje kumasoko yose, cyane cyane vinyl acetate na Ethylene copolymer ifu ya 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 cyane kwisi;
2. Uburambe bwo gusaba mubijyanye nubwubatsi nibyinshi;
3. Irashobora guhura nimiterere ya rheologiya isabwa na minisiteri (ni ukuvuga kubaka byubatswe);
4. Polymer resin hamwe nabandi ba monomers ifite ibiranga ibintu bito bihindagurika (VOC) na gaze irakaza;
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.
10. Biroroshye cyane guhuza hamwe na colloid ikingira (alcool polyvinyl) hamwe nibikorwa byinshi.
(2), ifu ya resin
Amenshi mu mafu ya "resin" polymer kumasoko arimo ibintu bya chimique DBP. Urashobora kugenzura ububi bwibi bintu byimiti, bigira ingaruka kumikorere yabagabo. Umubare munini wubwoko bwifu ya polymer yegeranijwe mububiko no muri laboratoire, kandi ifite ihindagurika runaka. Ku isoko rya Beijing, rizwi cyane kubera ubwinshi bwa "ifu ya polymer", ubu hariho "ifu ya polymer" yometse mumashanyarazi ifite amazina atandukanye: ifu ya polymer yihanganira amazi menshi, ifu ya resin polymer, nibindi biranga:
.
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. Bivugwa ko ikibaho cya XPS kidakenera 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 polymer".
ibitagenda neza:
1. Kurwanya ikirere cyumuti nikibazo kinini. 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.
incamake:
Ifu ya polymer isubirwamo:
1.
2. VAE isubirwamo ifu ya polymer ifitemo imiterere, firime 50% yumuti wamazi ikora 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. n'ubwubatsi, ifite ihinduka rikomeye muri anti-crack.
Ifu ya resin:
1. Ifu ya resin polymer ni ubwoko bushya bwibicuruzwa bihindura polymer, resin, polymer ndende, hamwe nifu ya polymer nziza.
2. Ifu ya resin polymer ifite uburebure muri rusange, kwambara birwanya, gutatanya nabi, bamwe bumva flocculent (igomba kuba ibikoresho byoroshye nka sepiolite), kandi hariho ifu yera (ariko ifite impumuro mbi isa na kerosene).
3. Ifu imwe ya resin yangirika ku kibaho, kandi kwirinda amazi ntabwo ari byiza.
4. Kurwanya ikirere no kurwanya amazi yifu ya resin polymer biri munsi yifu ya polymer. Kurwanya ikirere nikibazo gikomeye. Ku zuba, bizashira mu gihe gito. Nubwo yaba atari mwizuba, guhuza ibice bizakorwa Kuberako ari imyubakire yubusa, nayo izabora vuba.
5. Ifu ya resin polymer 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 kurwego rusanzwe.
6. Ifu ya resin polymer irashobora gukoreshwa gusa muguhuza imbaho za polystirene, kandi ntishobora gukoreshwa muguhuza amasaro ya vitrified hamwe nimbaho zidafite umuriro.
