6. La'akari da muhalli:
A cikin 'yan shekarun nan, an sami karuwar sha'awar haɓaka kayan gini masu dacewa da muhalli waɗanda ke rage tasirin muhalli. HPMC yana ba da fa'idodi da yawa dangane da wannan, saboda an samo shi daga albarkatu masu sabuntawa kuma yana da lalacewa a ƙarƙashin kyawawan yanayi. Sabili da haka, amfani da HPMC a cikin abubuwan da ake amfani da su yana ƙara ƙarfin amfani da kayan aiki kuma yana rage yawan sharar gida, don haka yana taimakawa wajen adana makamashi da albarkatu. Duk da haka, duk tasirin rayuwar rayuwar HPMC mai ƙunshe da putty, gami da abubuwa kamar hanyoyin masana'antu, sufuri da zubarwa, dole ne a yi la'akari da su don kimanta dorewar sa sosai.
Hydroxypropyl methylcellulose (HPMC) ƙari ne na multifunctional wanda zai iya tasiri sosai ga aikin putty a aikace-aikacen gini. Ƙarfin HPMC don canza kaddarorin rheological, haɓaka iya aiki, haɓaka kaddarorin inji da haɓaka karko yana sauƙaƙe haɓakar ƙirar sa mai inganci masu dacewa da buƙatu iri-iri. Koyaya, samun ingantaccen aiki yana buƙatar ƙira a hankali, la'akari da abubuwa kamar zaɓin matsayi, dacewa da abubuwan muhalli.
