Ifu ya Latex - Kunoza ubudahwema no kunyerera bya sisitemu muburyo bwo kuvanga amazi. Bitewe nibiranga polymer, guhuza ibikoresho byo kuvanga amazi bitose biratera imbere cyane, bigira uruhare runini mubikorwa; nyuma yo kumisha, itanga gufatira hejuru yubuso bworoshye kandi bwuzuye. Relay, utezimbere imikorere yumucanga, amabuye, na pore. Hashingiwe ku kwemeza ingano y’inyongera, irashobora gukungahazwa muri firime kuri interineti, kugirango ifatizo ya tile igire ihinduka runaka, igabanye moderi ya elastique, kandi ikurura impungenge ziterwa nubushyuhe bukabije. Mugihe cyo kwibiza mumazi mugihe cyakurikiyeho, hazabaho guhangayika nko kurwanya amazi, ubushyuhe bwa buffer, hamwe no guhindura ibintu bidahuye (coefficient de tile de tile 6 × 10-6 / ℃, coeffisente ya sima ya beto 10 × 10-6 / ℃) , no kunoza ikirere. Hydroxypropyl Methyl Cellulose HPMC - Gutanga amazi meza no gukora neza kubutaka bushya, cyane cyane ahantu huzuye. Kugirango habeho iterambere ryimikorere ya hydration reaction, irashobora kubuza substrate kwinjirira amazi menshi hamwe nubutaka bwo hejuru bugashira. Kubera umutungo wacyo uhumeka ikirere (1900g / L —- 1400g / LPO400 umucanga 600HPMC2), ubwinshi bwinshi bwumuti wa tile buragabanuka, kubika ibikoresho no kugabanya moderi ya elastike ya minisiteri ikomeye.
Tile yometseho isubirwamo ifu ya latx nicyatsi kibisi, cyangiza ibidukikije, cyubaka ingufu, cyujuje ubuziranenge bwibikoresho byinshi byubaka ifu, kandi nikintu cyingenzi kandi cyingenzi gikora mumashanyarazi yumye. Irashobora kunoza imikorere ya minisiteri, kongera imbaraga za minisiteri, kongera imbaraga zihuza hagati ya minisiteri nubutaka butandukanye, kunoza imikorere no gukora, imbaraga zo gukandamiza, imbaraga zoroshye, kwambara birwanya, gukomera, hamwe nubwiza bwa minisiteri. Ubushobozi bwo gufata amazi no gufata amazi, kubaka. Imikorere ya tile adhesive redispersible latex ifu irakomeye cyane, kandi ifu ya tile ifata redispersible latex ifu ifite ubushobozi bwo guhuza hamwe nibintu byihariye. Kubwibyo, urwego rwabo rwo gusaba ni rugari cyane. Uruhare rwa hydroxypropyl methylcellulose rufite uruhare rwo gufata amazi, kubyimba no gukora ibikorwa byubwubatsi hakiri kare, kandi ifu ya redispersible latex yifu ya tile yifata igira uruhare rwimbaraga mubyiciro byanyuma, bigira uruhare runini mugukomera, aside na alkali irwanya umushinga. Ingaruka ya tile adhesive redispersible powderx kuri minisiteri nshya: kongerera igihe cyakazi kandi uhindure igihe cyo kunoza imikorere yo gufata amazi, kugirango habeho hydrata ya sima no kunoza ubukana bwa sag (ifu idasanzwe ya rubber) kandi itezimbere gukora (byoroshye gukoresha Substrate nubwubatsi bwo hejuru, byoroshye gukanda amatafari mumatafari) uruhare rwa minisiteri ikomye ifatanye neza na substrate zitandukanye, zirimo beto, plaster, ibiti, amabati ashaje, PVC no mubihe bitandukanye byikirere, ifite ubushobozi bwo guhindura ibintu.
Kwiyongera kw'ifu ya redxersible latex ifata amatafari bigira ingaruka zigaragara cyane mugutezimbere imikorere yimikorere ya sima ishingiye kuri sima, kandi igira ingaruka zikomeye kumbaraga zihuza, kurwanya amazi, no kurwanya gusaza kwifata. Kugeza ubu, hari ubwoko bwinshi bwifu ya redxersible latex ifata kumatafari kumasoko, nka acrylic redispersible latex powder, ifu ya styrene-acrylic, vinyl acetate-etylene copolymers, nibindi. Amafu menshi ya redispersible latex ni vinyl acetate-Ethylene copolymers.

. , imbaraga zingana zingana ziyongereye cyane.
Bitewe nuburyo bwiza bwo gushushanya no gukora nko kuramba, kurwanya amazi no gusukura byoroshye, amabati yubutaka arakoreshwa cyane: harimo inkuta, amagorofa, igisenge hamwe n’ibidendezi byo koga, nibindi, kandi birashobora gukoreshwa haba murugo no hanze. Uburyo bwa gakondo bwo gushira amatafari nuburyo bwubatswe bwubatswe, ni ukuvuga, banza ushyireho minisiteri isanzwe inyuma yinyuma, hanyuma ukande amatafari kumurongo fatizo. Ubunini bwurwego rwa minisiteri ni 10 kugeza 30mm. Nubwo ubu buryo bubereye cyane kubwubatsi ku buringanire butaringaniye, ibibi ni imikorere mike yo kubumba amabati, ibisabwa cyane kugirango ubumenyi bwabakozi bukorwe, kongera ibyago byo kugwa bitewe n’imiterere idahwitse ya minisiteri, ndetse ningorabahizi mu gukosora minisiteri yubatswe. . Ubwiza bugenzurwa cyane. Ubu buryo bubereye gusa amabati afite umuvuduko mwinshi wo gufata amazi. Mbere yo gushira amabati, amabati agomba gushirwa mumazi kugirango agere ku mbaraga zihagije.
Kugeza ubu, uburyo bwo kubumba bukoreshwa cyane mu Burayi nuburyo bwitwa uburyo bworoshye bwo gufatira hamwe, ni ukuvuga ko polymer yahinduwe ya tile yometse ku gipande cyibanze kugirango ihambirwe mbere hamwe na spatula yinyo kugeza Ifishi yazamuye imirongo. Kandi igipimo cya minisiteri yubunini bumwe, hanyuma ukande kuri tile hejuru hanyuma uhindukire gato, ubunini bwurwego rwa minisiteri ni nka 2 kugeza 4mm. Bitewe no guhindura selile ya selile na pisitori ya latx isubirwamo, gukoresha iyi tile yifata bifite imikorere myiza yo guhuza ubwoko butandukanye bwibice fatizo hamwe nubuso burimo harimo amabati yuzuye vitamine yuzuye cyane, kandi afite ubworoherane, kugirango yinjire imihangayiko iterwa nibintu nko gutandukanya ubushyuhe, hamwe no guhangana neza na sag, igihe kinini gihagije cyo kubaka ibyoroshye, bishobora kwihutisha cyane umuvuduko wubwubatsi, byoroshye gukora kandi nta mpamvu yo kubanza guhanagura amabati mumazi. Ubu buryo bwo kubaka buroroshye gukora kandi byoroshye gukora ahabigenewe kugenzura ubuziranenge bwubwubatsi.
