Farqiga u dhexeeya Hydroxypropyl Starch ether iyo Hydroxypropyl Methylcellulose ee Dhismaha
Hydroxypropyl Starch Ether (HPSE) iyoHydroxypropyl Methylcellulose (HPMC)waa labada nooc ee polymers-ka biyaha ku milma inta badan loo isticmaalo warshadaha dhismaha. In kasta oo ay wadaagaan xoogaa isku mid ah, waxaa jira kala duwanaansho muhiim ah oo ku saabsan qaab-dhismeedkooda kiimikaad iyo sifooyinkooda waxqabad. Hoos waxaa ah faraqa ugu weyn ee u dhexeeya Hydroxypropyl Starch Ether iyo Hydroxypropyl Methylcellulose ee codsiyada dhismaha:
1. Qaabdhismeedka Kiimikada:
- HPSE (Hydroxypropyl Starch Ether):
- Laga soo bilaabo istaarijka, taas oo ah karbohaydrayt laga helo ilo kala duwan oo dhirta.
- Wax laga beddelay iyada oo loo marayo hydroxypropylation si kor loogu qaado hantideeda.
- HPMC (Hydroxypropyl Methylcellulose):
- Laga soo bilaabo cellulose, polymer dabiici ah oo laga helo gidaarada unugyada dhirta.
- Wax laga beddelay iyada oo loo marayo hydroxypropylation iyo methylation si loo gaaro guryaha la rabo.
2. Qalabka Isha:
- HPSE:
- Laga helay ilaha istaarijka ku salaysan dhirta, sida galleyda, baradhada, ama tapioca.
- HPMC:
- Laga soo bilaabo ilaha cellulose-ku-saleysan ee dhirta, badiyaa saxarka alwaax ama suufka.
3. Soluble:
- HPSE:
- Caadi ahaan waxay muujisaa milanka biyaha wanaagsan, taas oo u oggolaanaysa in si fudud loogu kala firdhiyo hababka biyaha ku salaysan.
- HPMC:
- Biyo aad u-milmi leh, samaynta xalal cad oo biyaha ah.
4. Kulaylka kulaylka:
- HPSE:
- Qaar ka mid ah ethers istaarijka hydroxypropyl ayaa laga yaabaa inay soo bandhigaan sifooyin kuleyl ah, halkaasoo viscosity ee xalku uu kordho heerkulka.
- HPMC:
- Guud ahaan ma muujiso kulaylka, viscositykeeduna wuxuu ahaanayaa mid xasiloon oo heerkul kala duwan ah.
5. Guryaha Samaynta Filimada:
- HPSE:
- Waxay samayn karaan filimo leh dabacsanaan wanaagsan iyo sifooyinka adhesion.
- HPMC:
- Waxay muujisaa sifooyinka samaynta filimada, ka qaybqaata horumarinta adhesion iyo isku xidhka qaababka dhismaha.
6. Doorka Dhismaha:
- HPSE:
- Loo isticmaalo codsiyada dhismaha ee dhumucdooda, haynta biyaha, iyo guryaha xabagta. Waxaa laga yaabaa in lagu shaqaaleeyo alaabada gypsum-ku-saleysan, hoobiyeyaal, iyo xabag.
- HPMC:
- Si weyn loogu isticmaalo dhismaha doorkeeda dhumuc ahaan, wakiilka biyaha haynta, iyo kor u qaadka shaqada. Waxaa caadi ahaan laga helaa hoobiyeyaal sibidh-ku-saleysan, xabag-dhoobo, grouts, iyo qaabab kale.
7. Waafaqid:
- HPSE:
- La jaanqaadi kara noocyo kala duwan oo lagu daro dhismaha iyo agabka kale.
- HPMC:
- Wuxuu muujiyaa ku habboonaanta wanaagsan ee qalabka dhismaha ee kala duwan iyo waxyaabaha lagu daro.
8. Wakhtiga dejinta:
- HPSE:
- Waxaa laga yaabaa inay saameyn ku yeelato waqtiga dejinta qaababka dhismaha qaarkood.
- HPMC:
- Waxay saamayn ku yeelan kartaa wakhtiga dejinta hoobiye iyo alaabta kale ee sibidhka.
9. dabacsanaan:
- HPSE:
- Filimada ay sameeyeen hydroxypropyl starch ethers waxay u muuqdaan kuwo dabacsan.
- HPMC:
- Waxay gacan ka geysataa dabacsanaanta iyo iska caabbinta dildilaaca qaababka dhismaha.
10. Goobaha Codsiga:
- HPSE:
- Laga helay noocyo kala duwan oo alaabooyin dhisme ah, oo ay ku jiraan malaasta, dhejiska, iyo qaababka xabagta.
- HPMC:
- Caadi ahaan loo isticmaalo hoobiye-cement-ku-saleysan, xabag-tile, grouts, iyo qalabka kale ee dhismaha.
Marka la soo koobo, halka labadaba Hydroxypropyl Starch Ether (HPSE) iyo Hydroxypropyl Methylcellulose (HPMC) ay u adeegaan ujeeddooyin isku mid ah dhismaha, asalkooda kiimikaad ee kala duwan, sifooyinka milanka, iyo guryaha kale waxay ka dhigayaan kuwo ku habboon qaababka iyo codsiyada kala duwan ee warshadaha dhismaha. Doorashada u dhaxaysa waxay kuxirantahay shuruudaha gaarka ah ee qalabka dhismaha iyo sifooyinka waxqabadka ee la rabo.
