Yuav ua li cas xaiv tus ntxhiab concentration ntawm scented tswm ciab ua los ntawm paraffin wax thaum kev cai txiav txim

Cov dab neeg:

Txhawm rau txhim kho kev sib tw ntawm cov khoom lag luam, qee lub chaw tsim khoom yuav pib lawv thawj cov lus hais ntawm 1% cov tshuaj tsw qab concentration. Thaum tus neeg siv khoom tsis paub meej tias cov tshuaj tsw qab ntau npaum li cas xaiv, cov lus hais qis dua yuav ua rau tus neeg yuav khoom muaj kev phooj ywg zoo. Nws yog illusion.

Tom qab 20 hnub, thaum koj tau txais cov qauv thiab pom tias koj tsis txaus siab rau cov ntxhiab tsw, qhov kev ua si yuav pib. Cov lus hloov kho tshiab nyob rau lub sijhawm tom ntej yuav zoo li nce toj ntaiv, thiab tus nqi yuav nce los ntawm kev dhia ib ncig.

Tom qab nkim sijhawm ntau, koj puas yuav xaiv tso tseg?

Raws li ib tug tswm ciab chaw tsim tshuaj paus nyob rau hauv Tuam Tshoj, niaj hnub no peb teb lo lus nug no los ntawm txawv wax ntaub ntawv:

Thawj qhov yuav tsum paub yog qhov ntawm cov roj yam tseem ceeb:

Cov roj tseem ceeb uas siv hauv cov tswm ciab tswm ciab yuav tsum yog oily, tsis yog cov roj uas muaj cawv-soluble tseem ceeb siv hauv cov tshuaj tsw qab. Yog vim li cas yog tias tag nrho cov ntaub ntawv siv quav ciab yog oily thiab lawv tuaj yeem yaj ua ke.

Paraffin wax ua scented tswm ciab:

(1) Cov tswm ciab ua los ntawm paraffin wax tsim nyob rau hauv Suav teb tuaj yeem sib xyaw txog li 7% concentration ntawm cov roj yam tseem ceeb thiab ncav cuag lub xeev saturated.

Tom qab qhov concentration ntawm cov roj tseem ceeb yog siab dua 7%, koj yuav pom tias cov kua roj tseem ceeb tsis tuaj yeem muab tso rau hauv qhov txias ciab thaiv.

Yog li ntawd, cov tshuaj tsw qab concentration ntawm 1% mus rau 7% yog muaj thiab tsis nkim.

(2) Feem ntau, cov neeg siv khoom zoo li Dollar General, Action, Walmart, thiab lwm yam, zoo ib yam li tus nqi qis hauv khw muag khoom yuav xaiv 1% ~ 3% fragrance concentration.

Yog tias qhov kev txiav txim kom muaj nuj nqis loj, txhawm rau txo cov nqi, cov neeg yuav khoom tseem yuav xaiv 1% tshuaj tsw qab concentration.

Tab sis tsis muaj leej twg yuav siv tsawg dua 1%.

(Nyob rau hauv peb 9 xyoo ntawm kev tsim tswm ciab, peb tau pom tiag tiag cov neeg yuav khoom tswm ciab uas tau thov kom siv cov khoom siv rov ua dua tshiab los ntawm cov tshuaj sulfuric acid kom tau txais tus nqi qis. Qhov no yog qhov yuam kev tuag.)

(3) Feem ntau ntawm kev txiav txim los ntawm cov neeg siv khoom zoo tib yam yuav xaiv cov tshuaj tsw qab ntawm 3% mus rau 5%.

Yog tias koj lub lag luam muaj cov kev xav tau siab dua ntawm cov tshuaj tsw qab, tab sis koj xav txuag cov nqi, koj tuaj yeem xaiv cov tshuaj tsw qab ntawm 3% -5% concentration kom phim cov tswm ciab ua los ntawm cov khoom siv paraffin. Txawm hais tias paraffin siv quav ciab tsis yog cov khoom siv ntuj tsim, cov tshuaj tsw qab tsis zoo, thiab lub sijhawm hlawv kuj tseem ntev.

(4) Tau kawg, qee cov neeg siv khoom yuav ntxiv 5% mus rau 7% ntawm paraffin wax. Lawv feem ntau yog los ntawm Middle East. Lawv xav tau qee hom tshuaj tsw qab uas muaj zog heev nrog rau cov tshuaj tsw qab siab.

Saum toj no:

1. Paraffin wax ua scented tswm ciab:

Kev txiav txim kom muaj nuj nqis loj (ntau tshaj 60K), rau kev nce qib, 1% -3% tshuaj tsw qab concentration tuaj yeem xaiv.

Qhov ntau npaum li cas (3K-30K), muaj qhov yuav tsum tau muaj rau cov tswm ciab tswm ciab, cov tshuaj tsw qab concentration ntawm 3% -5% yog qhov kev xaiv zoo.

Koj yog tus neeg siv khoom zoo li cas?
