Hydroxyemelcellulose (hec) ndi yosiyanasiyana komanso yogwira ntchito yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Dothi ili limachokera ku cellulose, polymer yachilengedwe imapezeka pamitundu yambiri m'malo obzala. Malo apadera a Hec amapangitsa kuti zikhale zabwino kuti zithetsa malonda osiyanasiyana, chifukwa cha zinthu zosamalira anthu pazinthu zopanga mafakitale.
Celluul mwachidule
Cellulose ndi chakudya chovuta chopangidwa ndi ma muler mamolekyu a glucose omwe amalumikizidwa ndi β-1,4-glycosiidic. Ndiye gawo lalikulu lazomera kukhoma la cell, ndikupatsa mphamvu ma cell tobzala maselo. Komabe, mawonekedwe ake azungu ndi okonda kugwiritsa ntchito magwiridwe antchito pazinthu zina.
cellulose zochokera
Pofuna kuwonjezera magwiridwe antchito a cellulose, zotumphuka zosiyanasiyana zasintha posintha mawonekedwe ake. Chimodzi mwazinthu zoterezi ndi hydroxethyl cellulose (hec), omwe ma hydroxyethyl magulu amayambitsidwa mu msana wa m'Chunji. Kusintha kumeneku kumapereka katundu wapadera, kumapangitsa kuti azisungunuka m'madzi komanso othandiza kwambiri ngati wokulirapo.
Mawonekedwe a hec
Kusalola
Chimodzi mwazinthu zazikulu za Hec ndi kukhazikika kwa madzi. Mosiyana ndi cellulose wachilengedwe, hec imasungunuka mosavuta m'madzi, ndikupanga yankho lomveka bwino. Izi zimapangitsa kukhala zosavuta kuphatikiza mitundu yosiyanasiyana.
Zovala za Rheogical
Hec amawonetsa machitidwe a pseudoplastic kapena shear, kutanthauza kuti ma viscy amachepetsa pansi pa kupsinjika kukameta ubweya ndikuwonjezeranso kupsinjika. Izi ndizofunikira kwambiri pazogwiritsa ntchito zomwe zimafuna kuti muzimitsa kapena kuthira, monga kufulumira kwa utoto, zomatira ndi zinthu zosamalira payekha.
Khalidwe
Hec ndi wokhazikika pamwamba pamitundu yosiyanasiyana, ndikupanga kukhala yoyenera kugwiritsa ntchito mu acidic, osalowerera ndale komanso alkaline. Kuchita kusintha kumeneku kwathandizira kuti mafakitale osiyanasiyana akhazikitsidwa monga zodzoladzola, mankhwala opangira mankhwala ndi chakudya.
Mapulogalamu a iyeC
Zogulitsa Zaumwini
Shampoos ndi zowongolera: Hec nthawi zambiri amagwiritsidwa ntchito popanga zinthu zosamalira tsitsi, kupereka mamasukidwe abwino ndikusintha mawonekedwe onse.
Kirimu ndi mafuta odzola: Mu mawonekedwe a khungu, hec imathandizira kukwaniritsa zomwe mukufuna ndikuwonjezera kufalikira kwa mafuta ndi mafuta.
Chikhalidwe cha dzino: ma pseudoplactic amathandizira mapangidwe opanga mano omwe amalola kufalitsa kosavuta ndikufalikira pakugwedezeka.
Utoto ndi zokutira
Utoto wa mochedwa: Hec amathandizira kuwonjezera kuwoneka ndi kukhazikika kwa utoto wa latex, kuonetsetsanso kugwiritsa ntchito pansi.
Zochita izi: Mu zomatira, Hec imathandizira kuwongolera mafakisoni ndikuwongolera katundu.
mankwala
Kuyimitsidwa kwa pakamwa: Hec imagwiritsidwa ntchito kufinya wam'madzi kuti apereke mawonekedwe okhazikika komanso osokoneza bongo a mankhwala.
Zovala zapamwamba: kusungunuka kwa hec m'madzi kumapangitsa kuti ikhale yoyenera kukhazikitsa ma gels apamwamba, kuonetsetsa kuti mayamwa agwiritse ntchito.
Makampani Ogulitsa Chakudya
Susula ndi mavalidwe: Hec imagwiritsidwa ntchito kuthira zisungunuke ndi zovala, kukonza kapangidwe kake ndi kamwa.
Zophika zophika: M'maphikidwe ena ophika, hec imathandizira matebulo ndi mtanda.
Kupanga ndi kuwongolera kwapadera
kaphatikizidwe
Hec nthawi zambiri amapangidwa ndi kusinthika kwa cellulose ndi ethylene oxide pansi pamakhalidwe olamulidwa. Mulingo wazolowa (DS) wa gulu la hydroxyathyl amatha kusinthidwa pa synthesis njira, motero amakhudza magwiridwe omaliza a HeC.
QC
Njira zowongolera zowongolera ndizofunikira kuti zitsimikizire ntchito za hec m'njira zosiyanasiyana. Magawo monga kulemera kwa ma celecular, kuchuluka kwa kuloweza ndi kuyera kumayang'aniridwa mosamala pakupanga.
Maganizo a chilengedwe
Monga ndi mankhwala pafupifupi amodzi, zinthu zachilengedwe ndizofunikira. Hec imachokera ku cellulose ndipo amakhala ndi biodegrablegrable kuposa ena opanga. Komabe, ndikofunikira kuganizira za kusintha kwachilengedwe pakupanga kwake ndikugwiritsa ntchito m'mapulogalamu osiyanasiyana.
Pomaliza
Mwachidule, hydroxyellulose (hec) imawoneka ngati yothandiza komanso yofananira ndi ntchito yamafakitale angapo. Zosiyanasiyana zake zapadera, kuphatikizapo kusungunuka kwamadzi, zachiwerewere ndi kukhazikika kwa pH, zimapangitsa kukhala chofunikira chofunikira pamapangidwe osiyanasiyana. Monga mafakitale akupitiliza kufunafuna njira zina zachitetezo, zomwe zili ndi biodegrade omwe zimachokera ku cellulose pa cellulose zimapangitsa kuti ikhale chisankho chokhazikika pamapulogalamu osiyanasiyana. Kupitiliza kufufuza ndi kuyanjana kwa cellulose monga Hec kungapangitse kuti zipitirize kupititsa patsogolo, kupereka magwiridwe antchito ambiri ndikuchepetsa mphamvu yachilengedwe.
