Hoʻohana
ʻO nā hoʻohana nui o ka phenolphthalein: 1. ʻOihana lāʻau lapaʻau ma ke ʻano he mea maka no ka lāʻau lapaʻau: He kūpono ia no ka paʻa mau a paʻakikī hoʻi a loaʻa i nā ʻano dosage like ʻole e like me nā papa a me nā suppositories. 2. No ka synthesis organik: Hoʻohana nui ʻia no ka synthesis o nā plastics, ʻoi aku hoʻi no ka synthesis o nā polymers diazazone polyaryletherketone. Loaʻa i kēia mau polymers ke kūpaʻa wela maikaʻi loa, ke kūpaʻa wai, ke kūpaʻa corrosion kemika, ke kūpaʻa wela a me ka hiki ke hana maikaʻi a me ke ʻano. Ua hoʻohana koke ʻia nā fibers, nā uhi a me nā mea i hana ʻia mai ia mea ma nā kahua e like me nā mea uila a me nā lako uila, nā lako mīkini, ka halihali, ka aerospace, ka ʻenekinia ikehu atomika a me ka pūʻali koa. 3. Hoʻohana ʻia ia ma ke ʻano he hōʻailona acid-base, he hōʻailona no ka titration solution non-aqueous, a me kahi reagent no ka nānā ʻana i ka chromatographic.
He mea hoʻohana maʻamau kēia huahana no ka hoʻololi ʻana i ke kala o ka pH 8.2 (kala ʻole) -10.0 (ʻulaʻula). He ʻano lāʻau lapaʻau nō hoʻi ka Phenolphthalein. Ma ke ʻano he laxative, hana ia ma ka colon a hoʻohana ʻia e mālama i ka constipation.
Hoʻohana ʻia ia ma ke ʻano he hōʻailona acid-base a me kahi laxative stimulant e mālama ai i ka constipation
Nā hōʻailona waikawa-kumu, nā hōʻailona titration hopena ʻaʻole wai, nā mea hana loiloi chromatographic.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
