Ubwino Wogwiritsa Ntchito HPMC Pamatope Odzikweza

The self-level mortar (SLM) ndi zinthu zapansi zowoneka bwino za simenti zomwe zimatha kugwiritsidwa ntchito pansi kuti apange malo osalala komanso opanda msoko. Zinthuzi zimagwiritsidwa ntchito kwambiri pomanga, monga mafakitale ndi malonda apansi pansi, nyumba zogona ndi mabungwe. Amagwiritsidwanso ntchito kukonzanso ndi kugwirizanitsa pansi pansi. Chimodzi mwazinthu zofunika kwambiri za SLM ndi hydroxypropyl methylcellulose (HPMC). HPMC ndi cellulose ether. Amagwiritsidwa ntchito ngati thickener, zomatira, emulsifier, stabilizer ndi kuyimitsidwa mu ntchito zosiyanasiyana ntchito zomangamanga. Nawa maubwino ogwiritsira ntchito HPMC pamatope odziyimira pawokha.

Kupititsa patsogolo processability

HPMC ndi multifunctional polima kuti akhoza ankagwiritsa ntchito simenti -zochokera pansi zipangizo. Imawongolera kuthekera kwa matope a matope popititsa patsogolo luso losunga la kusakaniza. Izi zikutanthauza kuti SLM ikhoza kukhala yotheka kwa nthawi yayitali, kotero kuti kontrakitala ali ndi nthawi yochulukirapo yoigwiritsa ntchito zisanachitike. HPMC imagwiranso ntchito ngati mafuta opangira mafuta, omwe amathandizira kuyendetsa bwino kwa SLM, komwe kumakhala kosavuta kugwiritsa ntchito ndikugawa mofanana.

Wabwino processability kusungitsa

Ubwino wina wa ntchito HPMC mu matope a kudzikonda mlingo ndi wapamwamba processability posungira makhalidwe. Mapangidwe a SLM ndi odziyimira pawokha, zomwe zikutanthauza kuti amatha kufalikira pamtunda wochiritsa. Komabe, kuchiritsa kungakhudzidwe ndi zinthu zingapo, monga kutentha kwa malo ozungulira, mlingo wa chinyezi, ndi makulidwe a wosanjikiza. HPMC kumathandiza kuchepetsa zotsatira za zinthu izi ndi kukhalabe processedability zinthu izi pa osakaniza. Zotsatira zake, pansi yomalizidwa imakhala yosalala.

Konzani kasungidwe ka madzi

Madzi amagwira ntchito yofunika kwambiri pakulimbitsa matope. Madzi ochepa kwambiri angayambitse zigawo zosalimba komanso zosalimba, ndipo madzi ochulukirapo angapangitse kuti zosakaniza zifooke ndikuphwanyidwa ndi kuuma. HPMC imathandizira kupititsa patsogolo luso losunga la SLM, potero kuchepetsa chiopsezo cha kutsika ndi kusweka. Izi zitha kuwonetsetsa kuti pansi pamakhala mawonekedwe olumikizana mwamphamvu komanso kukhazikika kokhazikika.

Kumamatira kwabwino

HPMC komanso timapitiriza kugwirizana makhalidwe a matope ake, potero kuwongolera kumamatira ake pa malo osiyanasiyana. Izi ndizofunikira makamaka pakuyika pansi komwe kulipo. Pansi yomwe ilipo, SLM iyenera kusungidwa mokwanira ndi malo akale kuti apange zokongoletsera zopanda msoko. HPMC imagwira ntchito ngati chomangira kuti tinthu ting'onoting'ono ta simenti tizimamatira pamodzi ndikumanga pamwamba. Izi zimapangitsa kuti pansi pakhale kukana kovala bwino, kumapangitsa kukhazikika, komanso kukana kukhudzidwa ndi kuphulika.

Makhalidwe apamwamba

Kuyenda kwa matope odziyimira pawokha ndikofunikira kuti mukwaniritse bwino kapena pamwamba. HPMC imakulitsa kuchuluka kwa magalimoto a SLM, kupangitsa kuti ikhale yosavuta kufalikira pamtunda. Izi zimachepetsa kufunikira kwa mauta ndi mivi mochulukira, zomwe zitha kupangitsa kuti pakhale kusafanana bwino kwapamtunda komanso kusalumikizana bwino. HPMC imatsimikiziranso kuti SLM ili ndi makhalidwe abwino kwambiri opingasa, kotero kuti pansi pakhale malo osalala, ofanana komanso osasinthasintha.

Kukana kwabwino kwa drooping

Ikagwiritsidwa ntchito pamtunda, SLM imatha kugwedezeka ndikusiya malo osagwirizana. HPMC imathandizira kukana kwa drooping kwa osakaniza powonetsetsa kuti imasunga mawonekedwe ake komanso kusasinthika pakagwiritsidwe ntchito. Izi zikutanthauza kuti kontrakitala atha kugwiritsa ntchito wosanjikiza wa SLM wokulirapo popanda kudandaula za kugwa. Chotsatira chake ndi chakuti pamwamba pake imakhala yomatira kwambiri komanso yosalala komanso yosalala.

Pomaliza

Kugwiritsa ntchito hydroxypropyl methyl cellulose (HPMC) kuli ndi maubwino ambiri popanga matope odziyimira pawokha. Zimapangitsa kuti SLM ikhale yotheka, imapangitsa kuti madzi aziyenda bwino, imapangitsa kuti ntchito ikhale yogwirizana, imapangitsa kuti ntchito ikhale yothamanga, imapangitsa kuti SAG isagwirizane, ndikuonetsetsa kuti malo omalizidwa ndi osalala, ofanana komanso osasinthasintha. Ubwino wogwiritsa ntchito HPMC pamadzi odziyimira pawokha umapangitsa kukhala chinthu choyenera pamafakitale osiyanasiyana, malonda, nyumba zogona, komanso ma projekiti apansi.
