Habka Diyaarinta Polycarboxylate Superplasticizer Lagu Sameeyay Heer kulka Qolka:
Hal-abuurku waxa uu la xidhiidhaa farsamada dhismaha isku-darka walxaha iyo gaar ahaan waxa ay la xidhiidhaa polycarboxylate superplasticizer oo lagu farsameeyay heerkulka qolka iyo habka diyaarintiisa.Habka diyaarinta wuxuu ka kooban yahay tillaabooyinka soo socda: ku darida polyether methyl allyl polyoxyethylene ether, hydrogen peroxide iyo 2-acrylamide tetradecyl sulfonic acid biyo deionized ah si loogu diyaariyo xal salka;daadinta xal A oo ka kooban acrylic acid, methacrylic acid iyo wakiilka wareejinta silsiladda mercaptoacetic acid iyo xal aqueous ah ee fitamiin C, walaaqaya si isku mid ah, fulinta falcelinta polymerization ee bilaashka ah heerkulka qolka, iyo nidaaminta qiimaha pH ee habka falcelinta inuu noqdo 6-7 adoo isticmaalaya soodhaha dareeraha ah ka dib marka falcelinta la dhammeeyo, si loo helo polycarboxylate superplasticizer.Polycarboxylate superplasticizer-ka laga helay hal-abuurku wuxuu ilaalin karaa kala-baxa muddada dheer, wuxuu leeyahay silsilado dhaadheer oo dheer, wuxuu ku fiican yahay xasilloonida kala firdhinta, fudud ee habka diyaarinta iyo isticmaalka tamarta yar, waxaa lagu dhejin karaa heerkulka qolka wuxuuna leeyahay faa'iidooyin dhaqaale oo wanaagsan.
Waxqabadka Hoobiye:
1. Waa isku mid u dhexeeya heerka biyo-yaraynta ee baabuurka iyo dareeraha koollada sibidhka.Dheecaannada badan ee koollada sibidhka, waa korodhka heerka biyo-yaraynta ee gaariga.
2. Heerarka yaraynta biyaha ayaa si degdeg ah u kordha marka qiyaasta la kordhiyo.Marka qiyaastu la mid tahay, heerka dhimista biyaha ee budada PCE waa 35% ka sarreeya kan superplasticizer kale ee suuqa.
3. Saamaynta ka imanaysa isku-darka isku-darka iyo isku-darka ciidda qalafsan awgeed, heerka biyo-yaraynta ee shubka wuu ka duwan yahay kan motar.Marka isku-darka isku-darka iyo isku-darka ciidda qallafsan ay door bidaan socodka shubka, heerka biyo-yaraynta ee shubka ayaa ka sarreeya kan motar.
4. Waxay leedahay waxqabad ka hortag ah marka heerkulku ka sarreeyo -5ºC.Markaa waxa loo isticmaali karaa shubka ka-hortagga-barafka.
Polycarboxylate Superplasticizer Astaamaha Alaabta:
1. Heerka yaraynta biyaha oo sarreeya: waxay ka dhigi kartaa heerka dhimista biyaha in ka badan 25%, waxayna si weyn u wanaajisaa dareeraha
iyada oo la raacayo xaalad isku mid ah oo biyo ah oo lagu daray shubka;
2. caabbinta sare ee hoos u dhaca: habka qalajinta buufinta, kooxda karboksilic waxay u keeni doontaa waxyeelo ka badan ama ka yar
polycarboxylate superplasticizer-dhaqameed.Si si weyn loo yareeyo waxqabadka haynta slump ka dib dareeraha waa
isu beddelay mid adag.Sp-409 waxaa lagu soo saaray hab gaar ah, si kooxda karboksylic acid aysan waxyeello u geysan
habka wax-soo-saarka budada ah, si loo sii hayo haynta hoos u dhaca khamriga hooyada dareeraha ah ee asalka ah.
3. milanka wanaagsan iyo heerka kala dirida degdega ah: sababtoo ah qaybo isku mid ah iyo bed gaar ah oo weyn.Sidaa darteed, way awoodaa
si dhakhso ah ayaa loo milmaan inta lagu jiro habka kala dirida biyaha.Oo ma jiraan wax wasakh ah oo muuqda ka dib kala diri.
Baaxadda Codsiga:
1. Ku habboon mashaariicda dhismaha ee fogfog nooca shubka bamgareynta.
2. Ku habboon isku-darka shubka caadiga ah, shubka wax-qabadka sarreeya, shubka xoogga badan iyo shubka xoogga aadka u sarreeya.
3. Ku habboon shubka aan fiicneyn, barafaysan iyo adkaysiga sarreeya.
4. Ku haboon shubka wax-qabadka sare leh iyo shubka qulqulaya oo sarreeya, shubka is-milaaya, shubka weji-caddaala ah iyo SCC
5. Ku haboon qiyaasta sare ee nooca budada macdanta ah.
6. Ku haboon shubka baaxada leh ee loo isticmaalo wadooyinka, tareenka, buundada, tunnel-ka, mashaariicda ilaalinta biyaha, dekedaha, biyaha badda, dhulka hoostiisa iwm.
Badbaadada iyo Feejignaanta:
1. Alaabtani waa alkalescence adag oo aan lahayn sun, daxal iyo wasakh.
Waa mid aan la cuni karin marka ay timaaddo jidhka iyo indhaha, fadlan ku dhaq biyo nadiif ah.Marka jirku xasaasiyad ku yeesho, fadlan qofka si degdeg ah ugu dir cusbitaal si uu u daweeyo.
2. Alaabtan waxaa lagu kaydiyaa foosto warqad ah oo ay ku jirto bacda PE-da gudaha.Ka fogow roobka iyo noocyada kala duwan ee aad isku dhex dartay.
3. Muddada dammaanadda tayada waa 12 bilood.
