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 gusubiramo.Ifu ya latx itandukanijwe, ubwo ni irihe tandukaniro riri hagati yifu ya resin reberi nifu ya redispersible powder, ifu ya resin ishobora gusimbuza ifu ya redispersible latex?Ikigo cy’ikoranabuhanga cya Yongqiang Mortar kizakuyobora gusesengura muri make itandukaniro riri hagati yibi byombi:
1. Ifu isubirwamo ifu ya latex
Kugeza ubu, ifu ya polymer ikoreshwa cyane ku isi ni: vinyl acetate na Ethylene copolymer rubber powder (VAC / E), Ethylene na vinyl chloride na vinyl laurate terpolymer rubber powder (E / VC / VL), acide acetike Vinyl ester na Ethylene hamwe na aside irike cyane vinyl ester terpolymer rubber powder (VAC / E / VeoVa), ifu ya polymer eshatu itatanye yiganje kumasoko yose, cyane cyane vinyl acetate na Ethylene copolymer rubber powder VAC / E / VeoVa E, ifite umwanya wambere kwisi yose umurima kandi byerekana tekiniki iranga tekinike ya polymer.Haracyari igisubizo cyiza cya tekiniki mubijyanye nuburambe bwa tekinike hamwe na polymers ikoreshwa muguhindura minisiteri:
1. Nimwe muma polymers akoreshwa kwisi;
2. Kugira uburambe bwo gusaba cyane mubikorwa byubwubatsi;
3. Irashobora kuzuza imiterere ya rheologiya isabwa na minisiteri (ni ukuvuga imirimo isabwa);
4. Polimeri isigarana nabandi ba monomers ifite ibiranga ibinyabuzima bito bihindagurika (VOC) hamwe na gaze nkeya;
5. Ifite ibiranga UV nziza cyane, irwanya ubushyuhe bwiza nigihe kirekire;
6. Ifite saponification yo hejuru;
7. Ifite uburebure bwagutse bwikirahure (Tg);
8. Ifite uburyo bwiza bwo guhuza, guhuza n'imiterere;
9. Kugira uburambe burebure mubikorwa bya chimique kuburyo bwo gukora ibicuruzwa byiza kandi byuburambe mugukomeza kubika neza;
10. Biroroshye guhuza hamwe na colloid ikingira (polyvinyl alcool) hamwe nibikorwa byiza.
Ifu ya resin
Amenshi mu mafu ya "resin" ya reberi ku isoko arimo imiti ya DBP.Urashobora kugenzura ububi bwibi bintu byimiti, bigira ingaruka kumikorere yabagabo.Umubare munini wifu ya rubber irundarunda mububiko no muri laboratoire, kandi birahindagurika kurwego runaka.Isoko rya Beijing, rizwi cyane mu gukora “ifu ya reberi”, ubu ryagaragaye ubwoko bwa “ifu ya rubber” yometse mu mashanyarazi ifite amazina atandukanye: ifu y’amazi menshi adashobora kwihanganira amazi, ifu yangiza, n'ibindi. :
1. Gutandukana nabi, bamwe bumva batose, bamwe bumva bafite flokculent (bigomba kuba ibintu byoroshye nka sepiolite), kandi bimwe byera kandi byumye gato ariko biracyafite impumuro nziza;
2. Impumuro nziza cyane;
3. Amabara amwe yongeyeho, kandi amabara agezweho ni umweru, umuhondo, imvi, umukara, umutuku, nibindi.;
4. Amafaranga yiyongereye ni make cyane, kandi amafaranga yiyongereye kuri toni imwe ni 5 ~ 12 kg;
5. Imbaraga zo hambere ziratangaje.Isima nta mbaraga ifite muminsi itatu, kandi irashobora kwangiriza ikibaho cyiziritseho.
6. Bavuga ko ikibaho cya XPS gishobora gukoreshwa nta agent wa interineti.
Binyuze mu ngero zabonetse kugeza ubu, dushobora kwemeza ko ari resin ishingiye ku gishishwa cyamamajwe n'ibikoresho byoroheje, ariko utanga isoko ashaka kwirinda ijambo "solvent" nkana, bityo ryitwa "ifu ya rubber"
ibitagenda neza:
1. Kurwanya ikirere cyumuti nikibazo gikomeye.Ku zuba, bizahinduka mugihe gito.Nubwo yaba atari ku zuba, interineti ihuza izangirika vuba kubera ubwubatsi;
2. Kurwanya gusaza, solvent ntabwo irwanya ubushyuhe, buriwese arabizi;
3. Kubera ko uburyo bwo guhuza ari ugusenya intera yinama yububiko, kurundi ruhande, nayo isenya intera ihuza.Niba hari ikibazo mubyiciro bizakurikiraho, ingaruka zizica;
4. Nta ntangarugero yo gusaba hanze.Hamwe nuburambe bukuze bwinganda shingiro zamahanga mumahanga, ntibishoboka kutavumbura ibi bikoresho.
incamake:
Ifu ya polymer itatanye:
1. Ibicuruzwa byifu ya redxersible latex nifu ya elegitoronike yamazi yisubiramo, ikaba kopolymer ya Ethylene na vinyl acetate, kandi ikoresha inzoga za polyvinyl nka colloid ikingira.
2. VAE isubirwamo 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 bipimo byigihugu.
4. Ifu ya redispersible latex ifitemo imikorere ihanitse: ifite ubushobozi bwo guhuza cyane, imikorere idasanzwe hamwe n’imikorere idasanzwe y’amazi adashobora gukoreshwa n’amazi, imbaraga nziza zo guhuza, guha minisiteri imbaraga zo kurwanya alkali nziza, kandi irashobora kunonosora imbaraga nimbaraga za minisiteri., plastike, kwambara birwanya no kubaka, bifite ihinduka rikomeye muri anti-crack.
Ifu ya resin:
1. Ifu ya reberi ya reberi ni ubwoko bushya bwo guhindura reberi, resin, macromolecular polymer, ifu ya reberi yubutaka nibindi bintu.
2. Ifu ya reberi ya rubber ifite uburebure muri rusange, irwanya abrasion, idakwirakwira nabi, bamwe bumva flocculent (igomba kuba ibikoresho byoroshye nka sepiolite), nifu 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, bizahinduka mugihe gito.Nubwo itari mu zuba, guhuza imiyoboro, Kubera ko ari inyubako yubatswe, nayo izabora vuba.
5. Ifu ya reberi ya reberi ntishobora guhinduka, cyangwa guhinduka.Ukurikije igipimo cyubugenzuzi bwa minisiteri yo hanze yinkuta zo hanze, gusa igipimo cyo gusenya ikibaho cya polystirene cyujuje ubuziranenge.Ibindi bipimo ntabwo bigera kurwego rusanzwe.
6. Ifu ya resin irashobora gukoreshwa gusa muguhuza imbaho za polystirene, ntabwo ari uguhuza amasaro ya vitrified hamwe nimbaho zidafite umuriro.
