Chinogodza mazino chinosimbisa sodium carboxymethyl cellulose (CMC)

Sodium carboxymethyl cellulose (CMC)i cellulose ether inokosha inonyungudika mumvura, inova anionic polymer compound inowanikwa ne alkalization uye etherification ye cellulose. Sechinhu chinosimbisa, chinosimbisa, chinosanganisa jira, chinoumba firimu uye chinonyorovesa zvine simba guru, CMC ine mashandisirwo akasiyana-siyana akakosha muindasitiri yemazino.

1. Basa guru reCMC mukurapa mazino

1.1. Mhedzisiro yekukora

Basa guru reCMC nderekukora. Zvinodiwa zvikuru zve toothpaste ndezvekuti paste inofanira kunge yakagadzikana zvakanaka, iine kuyerera kwakakodzera uye thixotropy, iri nyore kusvina kubva muchubhu ye toothpaste, uye kuchengetedza chimiro che paste panguva yekukwesha, uye kwete nyore kurasikirwa nayo. CMC inogona kugadzira colloidal solution yakajeka kana yanyungudutswa mumvura, iyo inogona kuwedzera viscosity ye toothpaste system uye kuita kuti paste ive nekugadzikana kwakanaka uye kugadzikana.

1.2. Gadzirisa chimiro che paste

Mushonga wemazino isystem inoumbwa nezvinhu zvakawanda (zvakadai semabrasives, masurfactants, manakiro, glycerin, mvura, nezvimwewo). CMC inogona kuita basa rakanaka mukumisa uye kudzikamisa, zvichiita kuti zvidimbu zvakasimba (zvakadai semabrasives) zviparadzirwe zvakaenzana mu matrix, kudzivirira kupatsanurwa, kusvibiswa uye kuparadzaniswa kwemvura, uye kuwedzera hupenyu hwesherufu yechigadzirwa.

1.3. Kuvandudza kubata uye kupararira kwechinhu

Mushonga weCMC une kupfava uye kunaka, izvo zvinogona kunatsiridza kuravira kwemushonga wemazino, zvichiita kuti uve munyoro kana uchishandiswa, usingatsamwise matadza, uye zvichivandudza ruzivo rwemushandisi. Panguva imwe chete, CMC ine hunhu hwakati hwekugadzira firimu, hunobatsira kugadzira firimu rinodzivirira uye hunodzivirira zvinyoro nyoro mumuromo.

1.4. Kusunungurwa kwakadzorwa uye kunyorovesa

Zvinhu zvinoshanda (zvakaita sefluoride, anti-allergic factors, nezvimwewo) zvinowedzerwa kune mamwe matomatisi anoshanda. CMC inogona kubatsira kudzora kuburitswa kwawo uye kuvandudza mashandiro ezvinoshandiswa zvinoshanda. Pamusoro pezvo, CMC ine kugona kwakasimba kwekunwisa hunyoro uye kunyorovesa, izvo zvinobatsira kudzivirira kuti toothpaste isaome uye isatsemuke uye inovandudza kugadzikana kwekuchengetwa.

2. Zvakanakira CMC pakushanda zvakanaka

2.1. Kunyungudika kwemvura yakawanda uye kuchengetedzeka

CMC inogona kunyungudutswa nekukurumidza mumvura inotonhora, iri nyore kushandisa, haidi kudziyiswa, uye inosangana nezvinodiwa zvekugadzira nekukurumidza zveindasitiri yemazino. CMC chigadzirwa chechisikigo chakagadziriswa nepolymer chine hukama hwakanaka uye chakachengeteka pamuromo. Hachina chepfu uye hachitsamwisi uye hachizokonzere migumisiro yakaipa pahutano hwevanhu.

2.2. Kugadziriswa kwakasimba kwe viscosity

Zvigadzirwa zveCMC zvine mhando dzakasiyana dzemhando dze viscosity (kazhinji 25 kusvika 8000mPa·s), izvo zvinogona kusarudzwa zvichienderana nezvinodiwa zvemaforomasi emazino, zvichiita kuti paste ive nyore kugadzira.

2.3. Kuenderana kwakanaka

CMC inoenderana zvakanaka nezvimwe zvinhu zvinoshandiswa mu toothpaste (zvakadai se glycerin, sorbitol, furo rinobvisa tsvina, rinogumbura, nezvimwewo), uye inoratidza kushanda kwakasimba mumasisitimu akasiyana.

3. Nzira dzekudzivirira pakushandisa CMC

Paunenge uchishandisa CMC mufomura yemazino, zvinhu zvinotevera zvinofanira kucherechedzwa:

Dzora huwandu hwekuwedzera: Huwandu hwekuwedzera hunobva pa0.5% kusvika 1.5%, zvichienderana nezvinodiwa kuti chigadzirwa chive chakasimba. Kushandiswa zvakanyanya kunogona kukonzera kuti paste ive yakakora zvakanyanya uye iome kuburitsa.

Nzira chaiyo yekunyungudutsa: Inofanira kuwedzerwa zvishoma nezvishoma mumvura kana yakakurungwa kuti isaite mapundu. Inogona zvakare kusanganiswa nezvinhu zvinonyorovesa zvakaita seglycerin pachine nguva uye yozowedzerwa mumvura kuti inyungudike kuti iwedzere kushanda zvakanaka kwekupararira kwayo.

Kuongorora kuenderana kweFormula: Inogona kunge iine maitiro asina kunaka nemamwe ma cationic surfactants kana munyu we inorganic une concentration yakawanda, uye bvunzo diki dzinofanira kuitwa kuti dzione kuenderana kwayo.

4. Kufambira mberi kweCMC muindasitiri yemazino

Nekuda kwekutarisa kwevanhu pahutano hwemuromo uye kukura kwakasiyana-siyana kwemazino anoshanda, zvinodiwa zvakanyanya zvinoiswawo pakushanda kwezvinhu zvemazino. Sechinyakare uye chakakura, chinzvimbo cheCMC chinoramba chakagadzikana. Zvisinei, kuti isangane nezvinodiwa zvakaoma zvemaitiro uye kuravira, indasitiri iri kugadzirawo masisitimu eCMC akagadziriswa (akadai se cross-linked, esterified, nezvimwewo) kana masisitimu ecompound (akadai seCMC ine xanthan gum, guar gum, nezvimwewo) kuti ivandudze mashandiro epaste. Pamusoro pezvo, kukwira kwezvinhu zvegirini, zvechisikigo uye zvine hushamwari kune zvakatipoteredza kwakasundidzirawo CMC kuti ikure nenzira yekuchena kwakanyanya, kusviba kwakaderera uye ether shoma.

Sechinhu chakakosha chinosimbisa uye chinosimbisafomura yemazino emazino sodium carboxymethyl cellulose (CMC)rave richishandiswa zvakanyanya mukugadzira mazino pasi rese nekuda kwehunhu hwaro hwakanaka hwemuviri nemakemikari, kuchengetedzeka uye hupfumi. Mune ramangwana, nekufambira mberi kwetekinoroji yekugadzira CMC uye kuvandudzwa kuri kuitwa zvigadzirwa zvemazino, CMC ichaita basa rakakosha mukuvandudza mhando yemazino uye ruzivo rwevashandisi.
