Game da Textile pH

1. Menene pH?

Ƙimar pH shine ma'auni na ƙarfin acid-tushe na bayani. Hanya ce mai sauƙi don nuna ƙaddamarwar ions hydrogen (pH = -lg [H +]) a cikin bayani. Gabaɗaya, ƙimar daga 1 ~ 14 kuma 7 shine ƙimar tsaka tsaki. Acidity na bayani ya fi karfi, ƙimar ya fi karami. Alkalinity na bayani ya fi karfi, darajar ya fi girma.

2.Muhimmancin gano pH

Fatar jikin mutum yana da rauni acid tare da ƙimar pH 5.5 ~ 6.0. Yanayin acid na iya hana haɓakawa da haifuwa na wasu ƙwayoyin cuta masu cutarwa da hana mamaye ƙwayoyin cuta na waje, kare fata daga kamuwa da cuta. Idan darajar pH ta wuce misali, kamar ma acid ko alkali, yanayin acid mai rauni na fatar mutum zai lalace, wanda ke haifar da ƙaiƙayi na fata ko rashin lafiyar fata.

3.Ka'idojin gano pH na yadi

Bayan dayadiana fitar da shi da ruwa mai tsafta ko tsaftataccen ruwa, yi amfani da mitar pH tare da lantarki na gilashi don auna ƙimar pH na ruwan barasa.

4.Dalilin darajar pH mai yadi ya wuce misali

(1) Tasirin rini yayin samarwa: Rini mai amsawa na yau da kullun da aka yi amfani da su, dyes vat da rini na sulfur suna aiki ƙarƙashin yanayin alkali. Ko da yake ana iya kula da farfajiyar zane da kyau ta hanyar wanke ruwa, ƙimar pH na ruwan samarwa zai shafi shi.

(2) Tasirin tsarin rini da bugu: Don auduga, ulu, siliki, polyester, nailan da acrylic, da sauransu, bayan haka.zazzagewa, rini da bugu, akwai ragowar alkali da sinadarai na acid da ƙarin taimako akan masana'anta, waɗanda ke da ƙimar pH daban-daban. Bayan yin magani ta hanyar wanke ruwa, sabulu, tsaka-tsakin acid da tsarin bushewa, da dai sauransu, idan adadin abubuwan taimako na sinadarai sun yi yawa ko kuma wanke ruwa bai isa ba, ƙimar pH na yadi zai wuce daidaitattun daidaito, wanda ke shafar sawa da yin amfani da aikin. textiles.

(3) Tasirin yadudduka: Kaurin yadudduka zai yi tasiri a saman zane. Don yadudduka na bakin ciki, yana da sauƙin wankewa bayan rini kuma ƙimar pH na saman zane yana da ƙasa. Don yadudduka masu kauri, yana da wuya a wanke bayan rini kuma ƙimar pH na saman zane ya fi girma.

(4) Tasirin kuskuren aiki na ma'aikatan dakin gwaje-gwaje: Daban-daban bushewa da zafi na masana'anta da aka gwada, yanayin hakar daban-daban da lokacin hakar daban, da sauransu zasuyi tasiri sakamakon ma'aunin pH akan farfajiyar zane.

5.Ingantattun matakan don yadudduka tare da pH mara kyau

(1) Acid-base neutralization: Idan partial acid, ƙara alkali zuwa neutralize. Idan partal alkali, ƙara acid zuwa neutralize. Gabaɗaya, shine ƙara acetic ko citric acid da sodium carbonate.

(2) Ingantawarinida tsarin gamawa: Ƙarfafa wanke ruwa, da dai sauransu.

(3) Zabi ɗanyen abu mai inganci da rini.
