Kwisakhiwo se-insulation mortar kunye ne-putty powder, ubukhulu be-hydroxypropyl methylcellulose ubumsulwa buchaphazela ngokuthe ngqo umgangatho wokwakhiwa kobunjineli, ngoko ke ziziphi izinto ezichaphazela ukucoceka kwe-hydroxypropyl methylcellulose?Ukukunceda ukuba uphendule lo mbuzo namhlanje.
Kwinkqubo yokuvelisa i-hydroxypropyl methylcellulose, i-oksijini eseleyo kwi-kettle yokusabela iya kubangela ukuthotywa kwe-hydroxypropyl methylcellulose kunye nokunciphisa ubunzima be-molecular.Nangona kunjalo, i-oksijini eshiyekileyo ilinganiselwe, ngoko akunzima ukuphinda udibanise iimolekyuli ezaphukileyo.Izinga lokuzalisa eliphambili kunye nomxholo we-hydroxypropyl unobudlelwane obukhulu, ezinye iifektri zifuna nje ukunciphisa iindleko kunye nexabiso, azifuni ukuphucula umxholo we-hydroxypropyl, ngoko umgangatho awukwazi ukufikelela kwinqanaba leemveliso ezifanayo zangaphandle.
Izinga lokugcinwa kwamanzi e-hydroxypropyl methylcellulose kunye ne-hydroxypropyl nalo linobudlelwane obukhulu, kwaye kuyo yonke inkqubo yokusabela, i-hydroxypropyl methylcellulose ikwamisela izinga lokugcinwa kwamanzi e-hydroxypropyl methylcellulose.Umphumo we-alkalization, umlinganiselo we-chloromethane kwi-propylene oxide, ukuxinwa kwe-alkali kunye nomlinganiselo wamanzi kwikotoni ecocekileyo yonke into inquma ukusebenza kwemveliso.
Umgangatho wemathiriyeli ekrwada, isiphumo se-alkalization, ulawulo lomlinganiselo wenkqubo, umlinganiselo we-solvent kunye ne-neutralization effect, zonke zimisela umgangatho we-hydroxypropyl methyl cellulose, enye i-hydroxypropyl methyl cellulose eyenziwe ukuba inyibilike emva kobisi olunamafu kakhulu, enye i-milky emhlophe, enye tyheli, enye. icace kwaye icace.Ukuba ufuna ukuyisombulula, lungisa kula manqaku angasentla.Ngamanye amaxesha i-acetic acid inokuchaphazela kakhulu ukuhanjiswa, i-acetic acid isetyenziswe kakuhle emva kokuhlanjululwa, impembelelo enkulu okanye i-reaction evuselelayo ifana, umlinganiselo wenkqubo uzinzile (ubumanzi obuthile bezinto eziphathekayo, umxholo awuzinzile, njengokubuyiswa kwe-solvent), eneneni, zininzi izinto ezichaphazelekayo.Ngokuzinza kwezixhobo kunye nokusebenza kwabaqhubi abaqeqeshiweyo, iimveliso eziveliswayo kufuneka zizinzile kakhulu.Ukuhanjiswa akufuneki kudlule kwi-±2%, kwaye ukuhambelana okufanayo kweqela elibambeleyo kufuneka kulawulwe kakuhle.Ukutshintshwa okufanayo, ukuhanjiswa kufuneka kube kuhle.
Ke ngoko, umgangatho olungileyo wemveliso umiselwa yimathiriyeli ekrwada, itekhnoloji yemveliso, kunye nezinye izinto.Ukulawula okungqongqo kuphela ukusuka kwelinye icala ukuya ekupheleni kunokuvelisa iimveliso ezinomgangatho ozinzile.
