RDP ee hoobiye isku qasan oo qalalan

Hoobiyaha isku qasan ee qallalan waa nooc isku dar ah oo isku dar ah oo isku dar ah oo isku dar ah oo isku dar ah oo isku dar ah iyo walxo sibidh ah oo aan organic ahayn. Waxaa goobta lagu geeyaa baabuur taangiyo gaar ah ama boorso warqad ah oo aan biyuhu karin, oo lagu qaso biyo. Hadda ka sokow sibidhka iyo ciidda tiro badan oo hoobiye isku dhafan oo qalalan, qaddarka intaa ka badan ayaa dib loo kala diri karaapolymer budada RDP. Sababtoo ah qiimaha sarreeya iyo saamaynta weyn ee guryaha hoobiye, waa diiradda dareenka dadka. Saamaynta dib loo kala diri karopolymer budada RDPku saabsan sifooyinka hoobiye ayaa looga hadlay warqaddan.

1 Habka Tijaabada

Si loo go'aamiyo saamaynta dib loo kala diri karopolymer budada RDPWaxyaabaha ku jira guryaha hoobiye polymer, Kooxo dhowr ah oo qaabeyn ah ayaa loo qaabeeyey habka tijaabada orthogonal waxaana lagu tijaabiyay sida ku cad dbjoi-63-2002, Heerka Kormeerka tayada ee polymer Mortar ee dahaarka dibadda ee derbiga dibadda, si loo go'aamiyo saameynta hoobiye polymer ee xajinta xoogga dammaanadda, cufnaanta dammaanadda xiiridda iyo xoogga is-xakamaynta, xoogga dabacsanaanta iyo saamiga dabacsanaanta ee hoobiye polymer ee salka la taaban karo.

Waxyaabaha ugu muhiimsan ee ceeriin waa P-04 2.5-pu sibidhka silikon; RE5044 iyo R1551Z dib ayaa loo kala firdhi karaa oo dib loo kala firdhi karaa budada emulsion; 70-140 mesh quartz ciid; Waxyaabaha kale ee lagu daro.

2 Saamaynta dib loo kala diri karopolymer budada RDPon sifooyinka hoobiye polymer

2.1 Curyaaminta xajinta iyo isku xidhka xidhidhiyaha xidhidhiyaha

Iyadoo kororka dib loo kala diri karopolymer budada RDPMawduuca, xoogga curaarta adkaysiga iyo xoogga xidhidhiyaha cufnaanta ee hoobiye polymer iyo hoobiye sibidhka ayaa sidoo kale kor u kacay, iyo shan qaloocood ayaa kor u kacaya barbar socda korodhka content sibidhka. Dhammaan dhibcooyinka khuseeya celceliska miisaanka, laakiin falanqaynta tirada ayaa lagu kala firdhi karaa nuxurka budada emulsion ee heerka saamaynta waxqabadka hoobiye sibidhka waxay arki kartaa in kororka budada emulsion ee dib loo isticmaali karo oo ku xiran xoogga isku-xidhka ee hoobiye sibidhka, polymer hoobiye cufan xoog xiiran. isbeddelka koritaanka tooska ah, isbeddelka guud ee 1% korodhka si uu u kala firdhiyopolymer budada RDP, xoogga isku xidhka ayaa kordhay 0.2 MPa, xoojinta dammaanadda xiirashada ayaa kordhay 0.45MPA

2.2 Guryaha cufan/ laablaabashada ee hoobiye laftiisa

Iyadoo kororka ka kooban ee dib loo kala diri karopolymer budada RDP, Xoogga cufan iyo xoogga dabacsanaanta ee hoobiye polymer ayaa hoos u dhacaya, taas oo muujinaysa in polymer-ku uu saameyn ku leeyahay fuuq-celinta sibidhka. FIG 4 waxay muujinaysaa saamaynta dib loo kala diri karopolymer budada RDPnuxurka ku saabsan isku-buufinta iyo saamiga laalaabida ee hoobiye polymer. , oo leh kororka maadada dib loo kala diri karopolymer budada RDP, Saamiga is-xakamaynta ee hoobiye polymer ayaa hoos u dhacaya, taas oo muujinaysa in polymer uu hagaajiyo adkaanta hoobiye. Saamaynta waxa ku jira dib loo kala diri karopolymer budada RDPku saabsan waxqabadka hoobiye polymer ayaa tiro ahaan lagu falanqeyn karaa celceliska miisaanka ee dhibic kasta oo isku xidhka. Iyadoo kororka ka kooban ee dib loo kala diri karopolymer budada RDP, xoogga cadaadiska, xoogga dabacsanaanta iyo saamiga dabacsanaanta ee hoobiye polymer ayaa muujinaya isbeddel toos ah oo hoos u dhacaya. Xoogga isku-buufinta, xoogga dabacsanaanta iyo saamiga dabacsanaanta ee dib loo kala firdhi karopolymer budada RDPayaa hoos u dhacay 1.21 MPa, 0.14MPa iyo 0.18 per 1%. Waxa kale oo la arki karaa in ay sabab u tahay kororka qadarka dib loo kala diri karopolymer budada RDP, dabacsanaanta hoobiye ayaa la hagaajiyay.

2.3 Falanqaynta tirada ee saamaynta saamiga sibidhka iyo ciidda ee sifooyinka hoobiye polymer

Madaafiicda polymer, saamiga sibidhka-cammuudka iyo dib loo kala firdhi karopolymer budada RDPcontent si toos ah ula falgalaan midba midka kale, sidaas darteed waxaa lagama maarmaan ah in laga wada hadlo saamaynta saamiga sibidhka-ciid si gooni gooni ah. Marka loo eego habka xogta tijaabada ee orthogonal waxay noqon doontaa isbarbardhig kala duwan sida doorsoomayaasha, kala firdhiso ayaa lala xiriirin karaapolymer budada RDPWaxyaabaha ay ka kooban tahay sida joogtada ah waxay barbardhigi kartaa saameynta isbeddelka ee jaantuska tirada hoobiye, waxay arki kartaa in kororka isbarbardhigga waxqabadka hoobiye polymer hoobiye iyo waxqabadka hoobiye polymer laftiisa ay si toos ah hoos ugu dhacayaan isbeddellada, isbeddelka guud waa in Xakamaynta xajinta ee hoobiye polymer ilaa hoobiye sibidhka ayaa hoos u dhacaya 0.12MPa, xoogga dammaanadda xiiridda ayaa hoos u dhacaya 0.37MPa, xoogga isku dhejinta ee hoobiye polymer ayaa hoos u dhacaya 4.14MPa, xoogga dabacsanaanta ayaa hoos u dhacaya 0.72MPa, iyo saamiga dabacsanaanku wuxuu hoos u dhacayaa 0.270 iyadoo la kordhinayo saamiga sibidhka iyo ciid kasta

3 Saamaynta dib loo kala diri karopolymer budada RDPIsku-xidhka xajinta ee u dhexeeya hoobiye polymer iyo guddiga EPS xumbo polystyrene DB JoI-63-2002 heerka caadiga ah wuxuu soo jeedinayaa in isku xidhka hoobiye polymer ee hoobiye sibidhka iyo guddiga EPS waa khilaaf.

Midka hore wuxuu u baahan yahay hoobiye polymer in uu ahaado mid adag, halka kan dambe uu u baahan yahay dabacsanaantiisa si uu u sarreeyo, laakiin tixgelinta injineernimada dahaarka dibadda labadaba si ay ugu dhejiyaan derbi adag iyo guddiga EPS ee dabacsan, isla mar ahaantaana si loo hubiyo in kharashka uusan ahayn mid aad u sarreeya. Sidaa darteed, saamaynta waxa ku jira dib loo kala diri karopolymer budada RDPHantida isku xidhka dabacsan ee hoobiye polymer ayaa si gooni ah loo taxay si loo xoojiyo muhiimada ay leedahay.

4Saamaynta noocyada dib loo kala diri karopolymer budada RDPxoogga isku xidhka guddiga EPS

R5,C1,P23 noocyada dib loo firdhiyopolymer budada RDPdibadda laga soo xulay. Taiwan D2,D4 2 nooc; Gudaha S1, S2 2 noocyada 7 nooc; Loox polystyrene ah oo laga sameeyay Beijing 18kg/ looxa EPS oo safan. Marka loo eego heerka dbJ01-63-2002, curaarta fidsan dib ayaa loo kala firdhi karaapolymer budada RDPGuddiga EPS waxay buuxin karaan shuruudaha waxqabadka curaarta xajinta adag ee dabacsan ee hoobiye polymer isku mar.
