Te Whakapaipai i nga Momo Moata Paura maroke me nga tauira taketake
1. whakarōpūtanga hua
① E ai ki te mahi o te raima moata, ka taea te wehewehe ki:
Ko te tikanga, ka taea te wehewehe i te kumete raima ki roto i te kumete raima noa, te kumete raima whakapaipai, te kumete raima parewai me te kumete raima me etahi mahi motuhake (pērā i te whakamahana wera, te aukati waikawa, me te moata tohu radiation).
② Whakar
A.Te whakakikorua i nga kumete ki te here parakore (ciment, gypsum, kotakota rewa ranei).
B.Ko nga mota stucco whakapaipai ma te whakamahi i te sima, te paura tukurua, te kotakota rewa ranei hei here.
C？Ka whakamahia nga raima i runga i te raima mo nga tono o waho me nga ruma maku, engari ko nga raima-a-gypsum ka whakamahia anake mo nga pakitara o roto.
2. tātai tohutoro
Mo te raima raima mo nga pakitara o roto me waho o nga pakitara pereki mahi kore-motuhake, he mea noa ake ki te whiriwhiri i te kaha compressive o 10MPa ranei 15MPa, engari ka taea hoki te hanga i nga hua iti-kaha me te kaha-kaha kia rite ki te motuhake motuhake. whakaritenga.
Ko te whakaaro tauira ko te taapiri i te 1% ~ 4% RE5010N ki te raima, ki te raima raima ranei, ka taea te whakapai ake i te piri, te mau atete me te ngawari.I tua atu, ka tūtohutia kia taapirihia te 0.2%~0.4% o te cellulose ether, te starch ether, te ranunga ranei o nga mea e rua.Ka tino taunakihia kia whakamahia te paura polymer redispersible RI551Z me te RI554Z me te hydrophobicity hei whakapai ake i te mahi o te raima me te raima.
Mortar Additive Masterbatch Introduction
Kei roto i te masterbatch taapiri moata nga waahanga e whai ake nei: te konutai ngako waipiro polyethylene sulfonate, te cellulose, te konutai konutai, te starch ether, etc.
Ko nga mahi matua: ko te hau-entraining, te matotoru, te kirihou-te pupuri, te whakanui i te mahi me etahi atu paanga ahurei, ko te hua anake i roto i te whenua e kore e uru ki runga i te tauwehenga papatipu ciment.Ko te whakaora i te ciment i roto i te kumete whakauru e kore e taea anake te whakarite i te kaha engari ano hoki te whakapai ake i te mauroa, te impermeability me te kapiti aukati.
Nga waahanga me nga waahanga mahi me nga waahanga mahi me nga waahanga mahi me nga mahi:
1. Whakapai ake i te mahi moata me te pai o te mahi
I te wa o te masonry me te raima, he nui te moata, he ngawari, he kaha te kaha o te whakakotahi.Ko te mata whakapiri kaore i te piri ki te koko, ka whakaiti i te pungarehu whenua me te utu, a he nui te whakakii o te moata.He iti nga whakaritenga mo te tohu o te makuku o te pakitara, me te iti o te paheketanga o te kumete, e hinga ana i nga raruraru noa penei i te pakaru, te pupuhi, te whakaheke, me te pupuhi i runga i te pakitara, me te whakaoti i te raruraru o te mahi moata.Ko te moata kei te rongoa mo nga haora 6-8 kaore he parataiao, he pai te pupuri i te wai, kaore he wehewehenga o te moata i roto i te pungarehu pungarehu, kaore he hiahia mo te whakaoho tonu, ka tere ake te tere o te hanga me te whakapai ake i te mahi mahi.
2. Painga kaha moata
Ko te kumete i konatunatua ki nga taapiri moata he hononga me te whakakaha ki te raima.Na roto i te tukanga plasticizing, ka tae ki tetahi kaha i muri i nga haora 5-6 o te whakamahinga, a ka pai ake te kaha o muri mai.
3. Tiaki wai
Ko te moata kua oti te whakarite me nga taapiri moata he paanga wehewehe ki te wai, ka taea te whakaiti i te kohi wai, te whakaiti i te whakahekenga o nga pakitara raima me te whakapai ake i te kaha.
4. Nga mahi taapiri
Ko te moata kua oti te hanga me nga taapiri moata ko nga mahi o te pupuri wai, te whakaheke haruru, te whakamarumaru wera, te whakamahana wera, me te aukati huka.
Te hanga me te tukanga whakaputa o te polyvinyl acetate emulsion adhesive
1. Tātai
Vinyl acetate: 710 kg
Wai: 636 kg
waipiro Vinyl waipiro polyvinyl (PVA): 62.5 kg
Ko te haukinia persulfate (kua whakamaua ki te 10 wa wai): 1.43 kg
Octylphenol ethoxylate: 8 kg
Te konutai bicarbonate (kua whakamaua ki te 10 wa wai): 2.2 kg
Dibutyl phthalate: 80 kg
2. Te tukanga whakaputa
Tāpirihia te waipiro polyvinyl me te wai ki roto i te kettle dissolution, ka whakaoho mo te 10 meneti ka wera ki te 90°C, ka memeha mo te 4 haora, ka rewa ki te otinga 10%.Whai muri i te tātari i te wairewa wai PVA kua memeha, maka ki roto i te tank polymerization, taapirihia te 100 kg o te octylphenol polyoxyethylene ether me te monomer tuatahi (mo te 1/7 o te tapeke o te monomer), me te waikawa persulfuric me te kukū o te 10% 5.5 kg o te haukinia. otinga, katia te poka whangai, ka whakatuwhera i te wai whakamatao.Ka timata te wera, ka piki ake ki te 65°C i roto i te 30 meneti.Ka puta mai nga topata wai ki roto i te karaihe tirohanga, kati te paera mamaoa (mo te 30-40 meneti), ka piki te pāmahana ki te 75-78°C.tinana (ka oti te taapiri i roto i nga haora 8-9).I te wa ano, taapirihia te 50 karamu o te haukinia persulfate i ia haora (kua whakahekehia ki te 10 nga wa o te wai).He tiketike rawa, he iti rawa ranei te paanga o te tauhohenga, a ka taea te whakahaere tika i te rerenga rere o te monomer taapiri me te nui o te kaitakawaenga, engari kaua e neke ake te tapeke o te tauira.Tuhia te ahua o te rewharewha me te pāmahana tauhohenga o te taapiri monomer ia 30 meneti, me te tuhi i te rerenga rerenga o te taapiri monomer me te nui o te kaitahuri ia haora.
Whai muri i te taapiri i te monomer, tirohia te pāmahana o te otinga tauhohenga.Mena he tiketike rawa (kei runga ake i te 85°C), ka taea te taapiri 440 karamu o te ammonium persulfate.95°C, whakamahana mo te 30 meneti, whakamatao ki raro iho i te 50°C, taapirihia te wairewa konutai bicarbonate.I muri i te kitenga kua tika te ahua o te whakaehunga, whakauruhia te dibutyl phthalate, whakaoho mo te 1 haora, ka tukuna.
