Lagu daro la taaban karo oo khafiif ah | Wakiilada Xumbaynta Waxqabadka Sare ee Shabka Gacanta
Shubka dabada leh ee miisaanka fudud waxa ku jira shubka xumbo leh iyo shubka hawo leh, oo leh sifooyinka miisaanka fudud, ilaalinta kulaylka iyo dahaarka, nuugista codka iyo dahaarka codka, ka hortagga dabka iyo gubasho la'aanta, iwm., Waa nooc ka mid ah agab cusub oo tamarta lagu badbaadiyo oo si weyn loogu isticmaalo dhismayaasha casriga ah. Si kastaba ha ahaatee, porosity sare awgeed, dusha weyn oo tamar bilaash ah, fududahay in la nuugo biyaha oo u horseeda xoogga iyo waxqabadka dahaarka ee dhimista, ka-hortagga barafka iyo dhalaalka iyo cimri dhererka dadka saboolka ah.Si gaar ah, nuugista biyaha dusha sare waa ay fududahay in ay keento qalajinta heerka yaraanta, iyo xoogga isku xidha ee malaasta dhibciyo, taasoo keentay in darbi madhan durbaan, caariyaysi, dildilaaca iyo daadinta dhul ballaaran, iwm., si dhab ah u saameeya dhismaha
Darbiga quruxda badan iyo nolosha adeegga.Sidaa darteed, hagaajinta waxqabadka biyuhu ee shubka dalool ee khafiifka ah ayaa noqda mawduuc cilmi baaris degdeg ah.
Iyada oo ku saleysan natiijooyinka cilmi-baarista ee jira, Wakiilka biyaha ee shubka daloola ee khafiifka ah waxaa loo kala saari karaa mid aan organic ahayn, isku darka organic iyo inorganic organic sida ay ka kooban kiimikada.
Farsamaynta ficilka biyaha celinaya
1. Wakiilka biyaha celiska ah ee silicone
Silikoon ama silikoon wakiilka biyaha celiya ee shubka dabada leh ayaa si weyn loogu fiirsaday cilmi-baarayaasha gudaha iyo dibaddaba., laakiin maaddooyinka ugu muhiimsan ee firfircoon waa alkyl silanolates, alkyl alkoxy silane iyo alkoxy.
Methyl Silicon alkoxide waa jiilkii ugu horreeyay ee walxo silikoon ah oo aan biyuhu lahayn, waxay masuul ka tahay inay daciifto aashitada CO2 ee hawada iyo biyaha si ay u abuurto aan milmi karin biyaha hoos yimaada ficilka methyl sodium silicate, mesh iyo falcelinta substrate la taaban karo si ay u sameeyaan poly hydrophobic (lakabka xuubka methyl siloxane, laakiin sababtoo ah xaaladaha alkali ee xooggan waxay dhalin doonaan aalkolo silikoon oo biyo ku milmaya, oo leh luminta qoyaanka biyuhu iyo luminta.
Silane loogu talagalay ilaalinta biyaha, inta badan waxa loola jeedaa tirada atamka kaarboon n ama ka badan 8 linear alkyl alkyl oxysilane.Kooxda difaaca organic ee Silane, kooxda r, hydrolyzes si ay u sameeyaan curaarta kaarboon-silikon ee deggan oo ku xidhan atamka silikoon, abuurista daahan hydrophobic leh tamar hoose oo ka hortagaysa in biyuhu galaan laakiin u oggolaanaya uumiga biyaha inuu galo ama ka tago shubka.
Silicone emulsion waxay ku salaysan tahay falcelinta qaybaha firfircoon ee kooxaha hydroxyl iyo kooxaha kale ee firfircoon ee dusha sare ee alaabta dabada silicate si ay u sameeyaan lakabka filimka biyaha ee shabakada oo leh biyo iska caabin ah. Si kastaba ha ahaatee., waxaa jira dhibaatooyin nolosha shelf gaaban iyo xasilloonida liidata ee emulsion emulsion water repellent.
Jaantus shaxeed ee habka falcelinta ee polymer organosilicon ee dusha shubka ah ee daloolka leh
2.Biyo cusbo leh oo dufan leh
Cusbada dufanka leh waa walax biyaha celisa. Marka hore, waa falcelin. Waxay ka kooban tahay kooxda karboksylic acid biyaha u adkaysta (– COOH ama — COONa) iyo Ca+ isku dar ah, Kaas oo isku dhafan oo lagu shubay dusha isku dhafka ah.Labaad, aan falcelin lahayn, Walxaha firfircoon ee waxtarka leh ayaa lagu daraa jaantuska waxaana lagu buuxiyaa daloolada gudaha shubka si loo yareeyo marinnada biyaha iyo nuugista biyaha.
3.Paraffin emulsion wakiilka biyaha celin
Paraffin ka dib sameynta emulsion surfactant ee emulsion paraffin, molecules paraffin emulsion, ka dib xannibaadda habka fuuq-baxa shubka ah ee daloolka gudaha iyo hadhuudhka si loo sameeyo xirmo walxaha, isbeddelka dusha sare ee hydrophilic ilaa hydrophobic, lakabka xuubka hydrophobic oo ka samaysan dhibco biyo shub ah oo daloola, yaree qoyaanka si uu uumi u baxo ka dib markaad ka baxdo daloolka, yaree nuugista biyaha ee shubka daloolsan.
4. Biyo-celiya-ka-soo-baxa crystalline-ka-salaysan
Biyo-qaadista biyaha-ka-hortagga ee crystalline (DPS) waa nooc ka mid ah wakiilka biyaha ka hortagga (DPS) taas oo ka faa'iidaysanaysa sifooyinkeeda crystallization oo si degdeg ah u gasha lakabka dusha sare ka dib markii ay la xiriirto alaabta la taaban karo, samaynta crystallization gudaha daloolada iyo xannibista gelitaanka iyo socodka molecules biyaha ee tuubooyinka xididka.
Cie-China.org waa hormoodka bixiyayaasha xumbo-samaynta la taaban karo ee bixiya wakiilka xumbo-samaynta, superplasticizer,xoojinta xoogga shubka xumbo ee shubka fudud, CLC blocks. Haddii aad raadinayso wakiil xumbo, fadlan xor u noqo nala soo xidhiidh.
