Ni izihe mpamvu nyamukuru zo gukuramo ifu yuzuye?

Ifu yuzuye ni ubwoko bwibikoresho byo gushushanya, ibice byingenzi ni ifu ya talcum na kole. Igice cyera hejuru yicyumba cyubusa cyaguzwe gusa. Mubisanzwe umweru wa putty uri hejuru ya 90 ° naho ubwiza buri hejuru ya 330 °.

Putty ni ubwoko bwibanze bukoreshwa mugusana urukuta, rushyiraho urufatiro rwiza rwintambwe ikurikira yo gushushanya (gushushanya na wallpaper). Putty igabanijwemo ubwoko bubiri: gushira imbere kurukuta no gushira kurukuta rwinyuma. Urukuta rwo hanze rushobora kurwanya umuyaga n'izuba, bityo rukagira gelation nziza, imbaraga nyinshi hamwe nubushakashatsi bwibidukikije. Igipimo cyuzuye cya putty murukuta rwimbere ni cyiza, kandi gifite isuku kandi cyangiza ibidukikije. Kubwibyo, urukuta rwimbere ntirukoreshwa hanze kandi urukuta rwo hanze ntirukoreshwa imbere. Ubusanzwe ibishishwa bishingiye kuri gypsumu cyangwa sima, bityo ubuso bubi bworoshye guhuza neza. Nyamara, mugihe cyubwubatsi, biracyakenewe koza urwego rwimikorere ya interineti kugirango rufunge urufatiro kandi rutezimbere urukuta, kugirango putty irusheho guhuzwa neza.

Abakoresha ifu ya putty benshi bagomba kwemera ko kugabanuka kwifu yifu ari ikibazo gikomeye. Bizatera irangi rya latex kugwa, kimwe no guturika no guturika kurwego rwa putty, bizatera gucamo irangi rya latex.

De-powder no kwera ifu ya putty kuri ubu nibibazo bikunze kugaragara nyuma yubwubatsi. Kugira ngo dusobanukirwe nimpamvu zitera ifu ya de-powder, tugomba mbere na mbere gusobanukirwa ibice fatizo byibanze byibanze hamwe n amahame yo gukiza ifu yimbuto, hanyuma tugahuza hejuru yurukuta mugihe cyo kubaka Amashanyarazi Kuma, kwinjiza amazi, ubushyuhe, kwumisha ikirere, nibindi.

Impamvu 8 zingenzi zitera ifu yuzuye.

impamvu imwe

Imbaraga zo guhuza za putty ntabwo zihagije zo gukuramo ifu, kandi uwabikoze agabanya buhumyi igiciro. Imbaraga zo guhuza ifu ya rubber irakennye, kandi umubare wongeyeho ni muto, cyane cyane kurukuta rwimbere. Kandi ubwiza bwa kole bufite byinshi byo gukora namafaranga yongeyeho.

Impamvu ya kabiri

Igishushanyo mbonera kidafite ishingiro, guhitamo ibikoresho nibibazo byubatswe nibyingenzi muburyo bwiza. Kurugero, hydroxypropyl methylcellulose (HPMC) ikoreshwa nkibishishwa bitarimo amazi kurukuta rwimbere. Nubwo HPMC ihenze cyane, ntabwo ikora kubuzuza nk'ifu ya kabiri yisazi, ifu ya talcum, ifu ya wollastonite, nibindi niba HPMC yonyine ikoreshwa, bizatera delamination. Nyamara, CMC na CMS hamwe nibiciro biri hasi ntibikuraho ifu, ariko CMC na CMS ntibishobora gukoreshwa nkibishishwa bitarinda amazi, cyangwa ntibishobora gukoreshwa nkurukuta rwinyuma, kuko CMC na CMS bifata ifu ya calcium yumukara na sima yera, bizatera gusiba. Hariho na polyacrylamide yongewemo ifu ya calcium ya lime na sima yera nkibishishwa bitarimo amazi, nabyo bizatera imiti yimiti itera gukuramo ifu.

Impamvu ya gatatu

Kuvanga bitaringaniye nimpamvu nyamukuru yo gukuramo ifu yo gukuramo putty kurukuta rwimbere ninyuma. Bamwe mu bakora inganda mu gihugu bakora ifu yuzuye ibikoresho byoroshye kandi bitandukanye. Ntabwo ari ibikoresho bidasanzwe byo kuvanga, kandi kuvanga kutaringaniye bitera ifu kuvanaho putty.

Impamvu ya kane

Ikosa mubikorwa byo kubyara ritera gushira ifu. Niba ivangavanga ridafite umurimo wo gukora isuku kandi hakaba hasigaye ibisigisigi byinshi, CMC muri putty isanzwe izitwara hamwe nifu ya calcium yivu ivu mumashanyarazi. CMC na CMS murukuta rwimbere rwashyizwe hamwe nurukuta rwo hanze sima yera ya putty ikora kugirango itere de-powder. Ibikoresho byihariye byamasosiyete bifite ibikoresho byogusukura, bishobora gusukura ibisigazwa byimashini, ntibireba gusa ubuziranenge bwibishishwa, ahubwo binakoresha imashini imwe mubikorwa byinshi, no kugura ibikoresho bimwe kugirango bitange ibintu bitandukanye. putty.

Impamvu ya gatanu

Itandukaniro mubyiza byuzuza naryo rishobora gutera de-powder. Umubare munini wuzuza ukoreshwa murukuta rwimbere ninyuma, ariko ibiri muri Ca2CO3 mubifu ya calcium iremereye hamwe nifu ya talc ahantu hatandukanye biratandukanye, kandi itandukaniro rya pH naryo rizatera de-powder ya putty, nkizo i Chongqing na Chengdu. Ifu imwe ya reberi ikoreshwa kurukuta rwimbere rwamavuta, ariko ifu ya talcum nifu ya calcium iremereye iratandukanye. Muri Chongqing, ntabwo ikuraho ifu, ariko muri Chengdu, ntabwo ikuraho ifu.

impamvu ya gatandatu

Impamvu yikirere nimpamvu yo gukuraho ifu yo gukuramo putty kurukuta rwimbere ninyuma. Kurugero, gushira kurukuta rwimbere ninyuma bifite ikirere cyumutse hamwe numwuka uhumeka neza mubice bimwe na bimwe byumye mumajyaruguru. Hariho ibihe by'imvura, ubuhehere bwigihe kirekire, imitungo ikora firime ntabwo ari nziza, kandi izanatakaza ifu, kuburyo uduce tumwe na tumwe dukwiriye gushiramo amazi adafite amazi ya calcium.

impamvu irindwi

Ibikoresho bidahuza nka porojeri ya calcium yifu na sima yera birahumanye kandi birimo ifu yisazi ebyiri. Icyitwa ifu yimyunyu ngugu ya calcium ikora hamwe na sima yera ikora kumasoko yanduye ku isoko irahumanye, kubera ko umubare munini wibi bikoresho byangiza umubiri udakoreshwa, kandi udashyira amazi mumazi yinkuta zimbere ninyuma byanze bikunze nta fu. kandi ntabwo ari amazi.

impamvu umunani

Mu mpeshyi, kubika amazi ya putty kurukuta rwinyuma ntibihagije, cyane cyane ahantu hafite ubushyuhe bwinshi no guhumeka nkinzugi ndende ndende nidirishya. Niba igihe cyambere cyo gushiraho ifu ya calcium yifu na sima bidahagije, bizabura amazi, kandi nibitabungabungwa neza, nabyo bizaba ifu ikomeye.
