Tuam Tshoj Chitosan cov chaw tsim khoom thiab cov chaw muag khoom

Chitosan

Cov chitosan qib kev lag luam feem ntau yog tsim los ntawm cov plhaub ntses hauv hiav txwv thiab cov plhaub ntses. Tsis yaj hauv dej, yaj hauv cov kua qaub dilute.

Chitosan qib kev lag luam muaj peev xwm muab faib ua: qib kev lag luam zoo thiab qib kev lag luam dav dav. Cov khoom lag luam qib kev lag luam sib txawv yuav muaj qhov sib txawv loj hauv qhov zoo thiab tus nqi.

Peb lub tuam txhab kuj tseem tuaj yeem tsim cov cim qhia raws li kev siv sib txawv. Cov neeg siv tuaj yeem xaiv cov khoom lawv tus kheej, lossis pom zoo cov khoom los ntawm peb lub tuam txhab kom ntseeg tau tias cov khoom ua tiav qhov kev siv xav tau.

Daim Ntawv Thov

1. Kev kho dej phwj tuaj: Chitosan tuaj yeem kho cov tshuaj uas raug tshem tawm hauv dej phwj, nqus qee cov hlau hnyav, thiab lwm yam, txo BOD thiab COD ntawm dej phwj, thiab chitosan kuj tseem siv tau rau hauv kev kho dej saum npoo av.

2. Cov Khoom Pab Txhawb Nqa Roj Av: Raws li cov yam ntxwv ntawm chitosan cov khoom macromolecule thiab amino zoo, chitosan kuj tseem siv tau rau hauv cov teb ntawm kev siv roj av thiab cov neeg pabcuam siv roj shale.

3. Kev ua ntawv: Cov hom chitosan tshwj xeeb siv tau ua tus neeg sawv cev ntsuas qhov loj me, tus neeg sawv cev txhawb nqa, kev pab khaws cia, thiab lwm yam hauv kev ua ntawv kom ua rau daim ntawv muaj zog dua thiab rov qab tau cov pulp uas ploj lawm.

4. Kev Ua Liaj Ua Teb: Chitosan siv tau rau hauv kev tsau noob, tus neeg sawv cev txheej, tshuaj tsuag nplooj, tus neeg sawv cev bacteriostatic, tshuaj kho av, khoom noj khoom haus ntxiv, txiv hmab txiv ntoo thiab zaub preservative, thiab lwm yam.

5. Chitosan kuj siv dav hauv lwm qhov chaw.
