Starch ether (mohiotia ano he whakahinuhinu polymer)

Ariā: He momo māngaro katote-kore i mahia e te tauhohenga whakaeera o te propylene oxide me te māngaro i raro i nga tikanga kawakore, e kiia ana ko te starch ether.Ko te maaka he maaka tapioka.I roto ia ratou, ko te ihirangi hydroxypropyl he 25%, he anti-thixotropic.Na te iti o te pokey, te hydrophilicity teitei, te pai o te wai, te ngoikore o te retrogradation me te pumau teitei, ka whakamahia nuitia i roto i te hangahanga me te umanga whakapaipai, penei i te hanga paura maroke, raima, pirihono hono me etahi atu mea koretake me te kawakore, te whakapai ake i te roto. te hanganga o te rauemi, me te pai o te hototahi ki nga taapiri kei roto, kia kaha ake te aukati i te hua ki te pakaru maroke, anti-sag, me te whakapai ake i te mahi me te mahi hanga.

Te ahua: te paura ma

āhuatanga:

1. Tino pai kaha thickening tere: pokey reo, pupuri wai tiketike;

2. He iti te inenga, a ka taea e te waahanga iti rawa te whakatutuki i te painga nui;

3. Whakapai ake i te kaha anti-sag o te rauemi ano;

4. He pai te whakahinuhinu, ka taea te whakapai ake i te mahi whakahaere o te rauemi, me te pai o te mahi.

Painga paerewa: 25kg

whakamahi:

Ka whakamahia te ether starch kua whakarereketia i roto i te hanga, te nuinga mo te whakapakeke me te aukati, me te cellulose ether te nuinga mo te pupuri wai, na reira ka whakamahia tahi me te cellulose ether;

Ka taea e ia te whakamaroke me te pupuri i te wai, te hanga i nga painga taapiri (kia rite ki te tauira, whakaitihia te nui o te HPMC ma te 30% ka whakakapi ki te maaka ether hei whakanui ake i te mahi hua)

Na roto i te whakamatautau, ka whakaarohia he pai ake te taapiri ki te taapiri i te hinu nui-nui ki te putty pakitara o waho i te taiao o te wera nui i te raumati.Ko te whakahinuhinu no te puhui polymer, a ko te whakahinuhinu rheological te nuinga o te whai ki te whakapai ake i te mahi hanga i roto i te punaha ciment.Te wa tuwhera me te mahi rite tonu.Ka whakanui ake i te kaha mahi me te tohe o te morta, te raima, te hanga, te raima me te whakapiri me te aukati i te whakamotitia o te sima whakataurite-whaiaro.Ko te take mo te pupuri i te wai he maha nga roopu mahi hydrophilic kei runga i tana mekameka ngota.I roto i te take o te muru me te paninga, e kore e ngaro te wai, he pai te mahi pupuri wai, me te matotoru me te thixotropy i te wa ano, kia maeneene te hanga, ka taea te whakakapi i tetahi waahanga, engari ko te utu he cellulose ether anake, a ko tona inenga he 0.5kg-1kg, he rauemi tino utu, mena ka whakamahia tahi me te cellulose ether, lignoscellulose, me te paura latex redispersible, ka pai ake te painga.
