Uruhare rw'ifu ya Latex mu gufunga amatafari

Ifu ya Latex—Kongera imiterere n'ubunyerere bw'iyi sisitemu mu gihe cyo kuvanga amazi. Bitewe n'imiterere ya polymer, uburyo ibikoresho bivanga amazi bihuzwa neza cyane, bigira uruhare runini mu gukora neza; nyuma yo kuma, bifasha gufatana n'urwego rworoshye kandi rwuzuye rw'ubuso. Kohereza, kunoza imikorere y'umucanga, amabuye n'imyenge. Mu rwego rwo kwemeza ingano y'inyongera, ishobora kongerwamo filime ku gice cyo hagati, ku buryo kole y'amatafari igira ubworoherane runaka, igagabanya modulus ya elastic, kandi ikagabanya ubushyuhe bwinshi. Mu gihe amazi yinjijwe mu gice cya nyuma, hazabaho imihangayiko nko kudahangana n'amazi, ubushyuhe bwa buffer, no kudahuza kw'ibikoresho (coefficient deformation tile 6 × 10-6 / ℃, coefficient deformation silence cement 10 × 10-6 / ℃), no kunoza ubudahangarwa bw'ikirere. Hydroxypropyl Methyl Cellulose HPMC—Itanga uburyo bwiza bwo kubika amazi no gukora neza ku kintu gishya, cyane cyane ahantu hatose. Kugira ngo amazi akomeze kugenda neza, bishobora kubuza ko substrate ifata amazi menshi kandi ko ubuso bwayo butavamo umwuka. Kubera ubushobozi bwayo bwo kwinjira mu mwuka (1900g/L—-1400g/LPO400 umucanga 600HPMC2), ubucucike bw'amatafari bugabanuka, bigatuma ibikoresho bizigama kandi bikagabanya uburyo bworoshye bwo gukoresha sima ikomeye.

Ifu ya latex ikoreshwa mu gukurura ibyuma ni iy'icyatsi kibisi, irinda ibidukikije, irinda ingufu, kandi ifite ubwiza bwinshi mu kubaka ifu, kandi ni inyongeramusaruro y'ingenzi kandi y'ingenzi ku gikoresho cyumye. Ishobora kunoza imikorere ya sima, yongera imbaraga za sima, yongera imbaraga zo gufatanya hagati ya sima n'ibindi bikoresho bitandukanye, yongera ubwiyongere n'ubushobozi bwo gukora, imbaraga zo gukanda, imbaraga zo guhindagurika, ubudasaza, gukomera, no gukomera kwa sima. Ubushobozi bwo gufatanya no kubika amazi, ubushobozi bwo kubaka. Imikorere y'ifu ya latex ikoreshwa mu gukurura ibyuma ni ikomeye, kandi ifu ya latex ikoreshwa mu gukurura ibyuma ifite ubushobozi bwo gufatanya bwinshi n'imiterere yihariye. Kubwibyo, uburyo ikoreshwamo ni bwinshi cyane. Uruhare rwa hydroxypropyl methylcellulose rugira uruhare mu kubika amazi, gukomera no gukora mu ntera ya mbere, naho ifu ya latex ikoreshwa mu gukurura ibyuma ifite uruhare rwo gukomera mu ntera ya nyuma, igira uruhare rwiza mu gukomera, aside na alkali by'umushinga. Ingaruka z'ifu ya latex ishobora kongera gushonga ku gikoresho gishya: kongera igihe cyo gukora no guhindura igihe kugira ngo amazi akomeze kubikwa neza, kugira ngo sima irusheho kuba nziza kandi yongere ubushobozi bwo kudacika (ifu yihariye ya rubber yahinduwe) kandi yongere ubushobozi bwo gukora (yoroshye gukoresha Substrate ni ubwubatswe hejuru, byoroshye gukanda amatafari mu gikoresho gishya) uruhare rwa sima ikomeye ifite uburyo bwo gufata neza ibintu bitandukanye, harimo sima, sima, imbaho, amatafari ashaje, PVC ndetse no mu bihe bitandukanye by'ikirere, ifite ubushobozi bwo guhindura ibintu neza.

Kongeramo ifu ya latex ishobora gusubirwamo mu gushushanya amatafari bifite ingaruka zigaragara ku kunoza imikorere y’amatafari ashingiye kuri sima, kandi bigira ingaruka zikomeye ku mbaraga zo gufatanya, kudapfa amazi, no kudashaza kw’amatafari. Kuri ubu, hari ubwoko bwinshi bw’amatafari asubirwamo mu gushushanya amatafari ku isoko, nka acrylic redispersible latex powder, styrene-acrylic powder, vinyl acetate-ethylene copolymers, nibindi. Muri rusange, amatafari asubirwamo akoreshwa mu gushushanya amatafari ku isoko Ifu nyinshi za latex zishobora gusubirwamo ni vinyl acetate-ethylene copolymers.

(1) Uko ingano ya sima yiyongera, imbaraga z’umwimerere z’ifu ya latex ishobora gusubirwamo yo gufunga amatafari ziyongera, kandi icyarimwe, imbaraga z’ifatizo nyuma yo kwinjizwa mu mazi n’imbaraga z’ifatizo nyuma yo gusaza ubushyuhe nazo ziyongera.

(2) Uko ingano y'ifu ya latex ishobora guhindurwa ikoreshwa mu gufunga amatafari yiyongeraga, imbaraga zo gufunga amatafari y'ifu ya latex ishobora guhindurwa ikoreshwa mu gufunga amatafari nyuma yo kwinjizwa mu mazi n'imbaraga zo gufunga amatafari nyuma yo gusaza ubushyuhe byariyongereye uko bikwiye, ariko ubushyuhe burushaho gusaza Nyuma y'ibyo, imbaraga zo gufunga amatafari ziyongereye cyane.

Bitewe n'imitako myiza n'imikorere yayo nko kuramba, kudakoresha amazi no koroshya gusukura, amatafari ya ceramic akoreshwa cyane: harimo inkuta, hasi, igisenge na pisine, nibindi, kandi ashobora gukoreshwa haba imbere no hanze. Uburyo gakondo bwo gupfuka amatafari ni uburyo bwo kubaka ahantu hanini, ni ukuvuga, banza ushyireho sima isanzwe inyuma y'amatafari, hanyuma ukandagire amatafari ku gice cyo hasi. Ubunini bw'urwego rwa sima ni hagati ya mm 10 na 30. Nubwo ubu buryo bukwiriye cyane mu kubaka ku rufatiro rutangana, ingaruka mbi ni ubushobozi buke bwo gupfuka amatafari, ibisabwa cyane ku buhanga bw'abakozi, ibyago byinshi byo kugwa bitewe no kudakomera neza kwa sima, ndetse no kugorwa no gukosora sima aho bubaka. Ubwiza buragenzurwa cyane. Ubu buryo bukwiriye gusa amatafari afite umuvuduko mwinshi wo kwinjiza amazi. Mbere yo gupfuka amatafari, amatafari agomba kwinjizwa mu mazi kugira ngo agere ku mbaraga zihagije zo gufatanya.

Muri iki gihe, uburyo bwo gushyira tile mu matairi bukoreshwa cyane mu Burayi ni uburyo bwitwa uburyo bwo gufata tile buciriritse, ni ukuvuga ko tile yahinduwe na polymer ishyirwa ku buso bw'urwego rw'ibanze kugira ngo ishyirweho tile mbere y'igihe hakoreshejwe spatula ifite amenyo kugira ngo ikore imirongo izamutse. Kandi urwego rwa mortier rufite ubugari bungana, hanyuma ukande tile kuri rwo hanyuma uzunguruke gato, ubugari bw'urwego rwa mortier bungana na mm 2 kugeza kuri 4. Bitewe no guhindura ether ya cellulose na latex ivuguruye, gukoresha iyi tile kole ifite imikorere myiza yo gufatanya n'ubwoko butandukanye bw'urwego rw'ibanze n'urwego rw'ubuso harimo n'amatafari yuzuye afite amazi make cyane, kandi ifite ubushobozi bwo koroha, ku buryo yakira stress iterwa n'ibintu nk'itandukaniro ry'ubushyuhe, no kudakomera cyane, igihe kirekire gihagije cyo kubaka tile kole, bishobora kwihutisha cyane umuvuduko w'ubwubatsi, byoroshye gukoresha kandi nta mpamvu yo kunywesha tile mbere y'igihe. Ubu buryo bwo kubaka bworoshye gukoresha kandi bworoshye gukora igenzura ry'ubuziranenge bw'ubwubatsi aho buherereye.
