Ukutyabeka Iintlobo zodaka lwePowder eyomileyo kunye neeFomula eziSisiseko
1. Ukuhlelwa kwemveliso
① Ngokomsebenzi wodaka lokutyabeka, lunokwahlulwa lube:
Ngokubanzi, udaka lokutyabeka lunokohlulwa lube ludaka oluqhelekileyo lokutyabeka, udaka lokutyabeka oluhombisayo, udaka lokutyabeka olungangeni manzi kunye nodaka lokutyabeka olunemisebenzi ethile (efana nokugquma ubushushu, ukumelana neasidi, nodaka olunobungqina bemitha).
② Ukuhlelwa ngokwemathiriyeli yesamente esetyenziswa kudaka lokutyabeka
A.Ukutyabeka iimbumba kunye nezibophelelo ezingaphiliyo (isamente, igypsum okanye i-slaked lime).
B.Iindonga zokuhombisa zestucco zisebenzisa isamente, umgubo okwaziyo ukuphinda-phinda uhlakazwe okanye i-slaked lime njengezibophelelo.
C.Iiplaster ezenziwe ngesamente zisetyenziselwa ukusetyenziswa kwangaphandle kunye namagumbi amanzi, ngelixa i-gypsum-based plasters isetyenziselwa kuphela iindonga zangaphakathi.
2. Ifomula yereferensi
Ngodaka lokutyabeka ngaphakathi kunye neendonga zangaphandle zeendonga zezitena ezingasebenzi ngokukhethekileyo, ngokuqhelekileyo kuxhaphake kakhulu ukukhetha amandla oxinzelelo lwe-10MPa okanye i-15MPa, kodwa amandla aphantsi kunye nemveliso yamandla aphezulu nayo inokwenziwa ngokuhambelana neyona nto ikhethekileyo. iimfuno.
Isiphakamiso sefomula kukongeza i-1% ~ 4% RE5010N kwi-samente okanye i-lime-samente esekelwe kwi-plaster yokugqiba, enokuphucula ukubambelela kwayo, ukuxhathisa ukunxiba kunye nokuguquguquka.Ukongezelela, kukwacetyiswa ukuba udibanise i-0.2% ~ 0.4% ye-cellulose ether, i-starch ether okanye umxube wazo zombini.Kucetyiswa ngokukodwa ukusebenzisa i-polymer powder edispersible RI551Z kunye ne-RI554Z kunye ne-hydrophobicity ukuphucula ukusebenza kokutyabeka kunye nokutyabeka.
Intshayelelo yeMortar Additive Masterbatch
I-masterbatch eyongeziweyo yodaka iqulethe la macandelo alandelayo: i-sodium fatty alcohol polyethylene sulfonate, i-cellulose, i-sodium sulfate, i-ether starch, njl.
Imisebenzi ephambili: i-air-entraining, i-thickening, i-plastic-retaining, i-performance-envigation kunye nezinye iziphumo ezikhethekileyo, imveliso kuphela yelizwe engaxubekiyo ngokomlinganiselo we-samente.Ukugcina i-samente kumdaka oxubeneyo akunakuqinisekisa kuphela amandla kodwa nokuphucula ukuqina, ukungagungqi kunye nokumelana nokuqhekeka.
Iimpawu kunye neempawu zokuSebenza kunye neMiba yokuSebenza kunye neMiba yokuSebenza kunye nokuSebenza:
1. Ukuphucula ukusebenza kodaka kunye nokusebenza kakuhle
Ngexesha lokwakha kunye nokutyatyekwa, udaka luninzi, luthambile, kwaye lunamandla okubambisana.Umphezulu oncangathi awuncangathi kumhlakulo, unciphisa uthuthu lomhlaba kunye neendleko, kwaye udaka luneqondo eliphezulu lokuzala.Ineemfuno eziphantsi kwiqondo lokumanzi kodonga, kwaye ukucutheka kodaka kuncinci, okoyisa iingxaki eziqhelekileyo ezinje ngeentanda, imingxuma, ukuphalala, kunye nogwebu eludongeni, kwaye isombulule ingxaki yokusebenza kodaka.Udaka lugcinwa kwiiyure ezingama-6-8 ngaphandle kwe-sedimentation, ukugcinwa kakuhle kwamanzi, akukho ukwahlulwa kodaka kwitanki yothuthu, kwaye akukho mfuneko yokuvuselela ngokuphindaphindiweyo, okukhawulezisa isantya sokwakha kunye nokuphucula ukusebenza kakuhle.
2. Isiphumo samandla sakwangoko
Udaka oluxutywe kunye nezongezo zodaka lunobudlelwane kunye nokuqinisa amandla ngesamente.Ngokusebenzisa inkqubo yeplastiki, ifikelela kumandla athile emva kweeyure ezingama-5-6 zokusetyenziswa, kwaye amandla kamva angcono.
3. Ukonga amanzi
Udaka olulungiselelwe ngezongezo zodaka lunempembelelo yokwahlula kumanzi, anokunciphisa ukusetyenziswa kwamanzi, ukunciphisa ukuncipha kweendonga ezityatyekiweyo kunye nokuphucula amandla.
4. Imisebenzi eyongezelelweyo
Udaka olulungiselelwe ngezongezo zodaka lunemisebenzi yokugcina amanzi, ukunciphisa ingxolo, ukugcina ubushushu, ukugquma ubushushu, kunye nokumelana neqabaka.
Ukuqulunqwa kunye nenkqubo yokuvelisa i-polyvinyl acetate emulsion adhesive
1. Ifomula
I-acetate yevinyl: 710 kg
Amanzi: 636 kg
