Sida loo hagaajiyo dareenka gacanta culus ee xoqidda suufka

su'aal:

Putty waxa uu dareemaya culays

Inta lagu jiro dhismaha putty, dadka qaar ayaa la kulmi doona xaaladda ay gacanta ku dareemeyso culeys. Waa maxay sababta gaarka ah? Sidee loo hagaajin karaa?

Sababaha caadiga ah ee ay putty dareemeyso culus waa:

1. Isticmaalka khaldan ee qaabka viscosity ee ether cellulose:

Xaaladdan oo kale, viscosity ee ether cellulose guud ahaan waa mid aad u sarreeya, iyo putty la sameeyey waxay dareemi doontaa culus inta lagu jiro habka xoqidda;

Sababta kale ayaa ah in inta lagu jiro dhismaha xagaaga, isticmaalka hydroxypropyl methylcellulose ether oo leh caabbinta heerkulka sare ee liidata waxay keeni kartaa in suufku lumiyo viscosity, taas oo saameyn doonta dareenka dhismaha.

2. Saamiga khaldan ama ganaaxa budada:

Guud ahaan, waxaa jira waxyaabo badan oo gelling ah oo aan dabiici ahayn, ama ganaaxa buuxinta la doortay ayaa aad u fiican, kaas oo u nugul inuu ku dhejiyo mindida;

Waxa kale oo suurtogal ah in si loo yareeyo kharashka, ma jiraan ama ka yar wax lagu daro si loo hagaajiyo dareenka gacanta, sida istaarijka ethers iyo saliidaha thixotropic.

Siyaabaha loo horumariyo 1

Saamiga alaabta ceeriin ee habboon iyo xulashada ganaaxa

Wanaajinta alaabta ceeriin ee guud ahaan waxaa lagu xakameyn karaa 150-200 mesh, iyo ganaaxa buuxintu guud ahaan waxay noqon kartaa 325 mesh, ma aha mid aad u fiican;

Qadarka khamriga polyvinyl-ka budada ah waa inuusan ka badnaan 6%;

Waxa kale oo lagama maarmaan ah in la barto si loo yareeyo qadarka alaabta sibidhka ee aan organic. Guud ahaan, waa ku filan in la xakameeyo sibidhka 28% -32%, oo la isticmaalo wax lagu daro si ay si buuxda u horumariso waxqabadkeeda.

Habka hagaajinta 2

Dooro eter cellulose saxda ah

Guud ahaan, waxaan kugula talineynaa hydroxyethyl methyl cellulose ether oo leh waxqabad wanaagsan, kaas oo leh iska caabin heerkul sare oo wanaagsan oo si fiican loola qabsan karo dhismaha xagaaga iyo dhimista kharashka jiilaalka iyo xagaaga;

Furaha ayaa ah in la doorto ether-ka cellulose oo leh viscosity ku habboon. Guud ahaan, ether cellulose leh viscosity of 80,000 ilaa 100,000 ayaa ku filan budada putty, laakiin qadarka etherka cellulose ee lagu daray waa in lagu go'aamiyaa iyada oo loo marayo tijaabooyin dhismo macquul ah!

Ku dar waxyaabo lagu daro si aad u wanaajiso dareenka gacanta

Ugu dambeyntii, waxaan tixgelin karnaa in lagu daro istaarijka ether ama thixotropic lubricant (bentonite) si loo hagaajiyo dareenka hoobiye;

Xusuusnow: isku darka qaacidada sayniska ayaa fure u ah xallinta dhibaatada!
