Mono Propylene Glycol
Whakaahuatanga Hua
He wai kore tae me te pokey tonu me te pai o te whakauru wai.
Kare e hongi, kare e mura, he iti noa te paitini. Ko 76.09 tōna papatipu rāpoi. Ko tona pokey (20oC), te kaha o te wera motuhake (20oC) me te wera huna o te vaporization (101.3kpa) he 60.5mpa.s, 2.49KJ/(kg. oC) me te 711KJ/kg.
Ka taea te konatunatua me te whakaoti ki te waipiro, te wai me nga momo matū waro.
Ko te Propylene Glycol te rauemi mata mo te whakarite i te kapia polyester haunga, te kaiparapara, te kaihoko kaha o te mata, te kaihoko whakaemi me te kaihoko whakaheke.
Ka taea hoki te whakamahi hei aukati i te pokepokea ai, hei patu mo nga hua, te aukati huka me te makuku tiaki mo te tupeka.
