Eminye imibuzo ehlala ibuzwa malunga neputty powder

1. Iputty powder yoma ngokukhawuleza

Impendulo: Oku kuhambelana kakhulu nokongezwa kwe-ash calcium kunye nesantya sokugcinwa kwamanzi kwifiber, kunye nokuhambelana nokomisa kwodonga.

2. I-putty powder i-petty kunye ne-rolls

Impendulo: Oku kuhambelana nesantya sokugcinwa kwamanzi, okulula ukuba kwenzeke xa i-viscosity ye-cellulose iphantsi okanye inani lokongezwa lincinci.

3. Iputty powder de-powdering

Impendulo: Oku kuhambelana nomlinganiselo we-ash calcium eyongeziweyo, kwaye ihambelana nomlinganiselo kunye nomgangatho we-cellulose eyongeziweyo. Kubonakaliswa kwizinga lokugcinwa kwamanzi kwimveliso. Izinga lokugcinwa kwamanzi liphantsi kwaye ixesha le-hydration ye-ash calcium ayanele.

4. Iputty ngumgubo ogwebu

Impendulo: Oku kuhambelana nokufuma okomileyo kunye nokunyuka kodonga, kwaye kunxulumene nokwakhiwa.

5. Amanqaku avela kwiputty powder

Impendulo: Oku kuhambelana ne-cellulose, eneempawu ezimbi zokwenza ifilimu, kunye nokungcola kwi-cellulose kusabela kancinci nge-ash calcium. Ukuba ukusabela kubukhali, i-putty powder iya kuba kwimeko yentsalela yebhontshisi. Ayinakubekwa eludongeni, kwaye ayinayo amandla obumbano ngexesha elinye. Ukongeza, le meko iyenzeka nakwiimveliso ezinje ngamaqela e-carboxyl afakwe kwiselulosi.

6. Imiqolomba yentaba-mlilo kunye nemingxuma yokuqhambuka iyavela

Impendulo: Oku ngokucacileyo kunxulumene noxinzelelo lomphezulu wamanzi we-hydroxypropyl methylcellulose isisombululo samanzi. Uxinzelelo lwetafile yamanzi kwisisombululo samanzi se-hydroxyethyl ayicacanga. Kuya kulunga ukwenza unyango lokugqiba.

7. Emva kokuba i-putty yomile, kulula ukuqhekeka kunye nokujika kwephuzi

Impendulo: Oku kuhambelana nokongezwa kwenani elikhulu le-gray calcium. Ukuba ubuninzi be-calcium egrey bongezwa kakhulu, ubunzima be-putty powder buya kunyuka emva kokumisa. Ubunzima kuphela kwaye akukho bhetyebhetye kuya kuqhekeka ngokulula, ngakumbi xa iphantsi kwamandla angaphandle. Ikwanxulumene nomxholo ophezulu we-calcium oxide kwi-gray calcium, eyaziswa ngaphambili.

8. Kutheni i-putty powder iba ncinane emva kokufaka amanzi?

Impendulo: I-Cellulose isetyenziswe njenge-thickener kunye ne-agent egcina amanzi kwi-putty. Ngenxa ye-thixotropy ye-cellulose ngokwayo, ukongezwa kwe-cellulose kwi-putty powder kukhokelela kwi-thixotropy emva kokongeza amanzi kwi-putty. Le thixotropy ibangelwa ukutshatyalaliswa kwesakhiwo esidibeneyo samacandelo kwi-putty powder. Esi sakhiwo sivela ekuphumleni kwaye siphule phantsi koxinzelelo. Oko kukuthi, i-viscosity iyancipha phantsi kokuvuselela, kwaye i-viscosity iphinda ibuyele xa imile.

9. Kutheni iputty inzima kwinkqubo yokukhuhla?

Impendulo: Kule meko, i-viscosity ye-cellulose esetyenziswa ngokubanzi iphezulu kakhulu. Abanye abavelisi basebenzisa i-200,000 yeselulosi ukwenza i-putty. I-putty eveliswe ngolu hlobo ine-viscosity ephezulu, ngoko ivakalelwa kakhulu xa ikhuhla. Isixa esicetyiswayo se-putty powder kwiindonga zangaphakathi yi-3-5 kg, kwaye i-viscosity yi-80,000-100,000.

10. Kutheni i-putty kunye ne-mortar eyenziwe nge-cellulose ene-viscosity efanayo ivakalelwa ngokwahlukileyo ebusika nasehlotyeni?

Impendulo: Ngenxa ye-thermal gelation yemveliso, i-viscosity yemveliso iya kuncipha ngokuthe ngcembe ngokunyuka kweqondo lokushisa. Xa iqondo lokushisa lidlula ukushisa kwe-gel yemveliso, imveliso iya kuhlanjululwa emanzini kwaye ilahlekelwe yi-viscosity yayo. Ukushisa kwegumbi ehlotyeni ngokuqhelekileyo kungaphezulu kwama-30 degrees, okuhluke kakhulu kwiqondo lokushisa ebusika, ngoko i-viscosity iphantsi. Kucetyiswa ukuba ukhethe imveliso ene-viscosity ephezulu xa usebenzisa imveliso ehlotyeni, okanye ukwandisa inani leselulosi, kwaye ukhethe imveliso enobushushu obuphezulu bejeli, zama ukusebenzisa iimveliso zebakala leMK, ubushushu bejeli balo mveliso buphakathi. Ngaphezulu kwama-70 degrees. Zama ukungasebenzisi i-methyl cellulose ehlotyeni, ubushushu bayo bejeli bumalunga nama-55 degrees.
