Itandukaniro riri hagati yifu ya polymer nifu ya resin

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 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.

(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:

1. Gutandukana nabi, bamwe bumva batose, bamwe bumva flocculent (bigomba kuba ibintu byoroshye nka sepiolite), 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 polymer".

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.

incamake:

Ifu ya polymer isubirwamo:

1. Igicuruzwa cya pisitori ya polymer isubirwamo ni ifu ya elegitoronike isubirana ifu, ikaba ari kopolymer ya Ethylene na vinyl acetate, hamwe na alcool ya polyvinyl nka colloid ikingira.

2. Ifu ya VAE isubirwamo ifu ya polymer 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. Ifu ya polymer isubirwamo ifite imikorere ihanitse: ifite ubushobozi bwo guhuza cyane, imikorere idasanzwe hamwe n’imikorere idasanzwe y’amazi, imbaraga nziza zo guhuza, itanga minisiteri irwanya alkali nziza, 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 resin polymer ni ubwoko bushya bwo guhindura ibicuruzwa kuri 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 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 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. Resin polymer ifu 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.
