Nws yog dav siv nyob rau hauv ib tug ntau yam ntawm teb - tshuaj no, thiab khoom noj khoom haus ntau lawm, thiab hluav taws xob engineering. Sim kom to taub txog lub thaj chaw ntawm cov khoom no thiab nws cov ntaub ntawv.

Paraffin - dab tsi yog qhov no?

Qhov saum toj no-hais substance yog ib tug khoom sib tov ntawm siab txaus hydrocarbons limiting cim. Muaj pes tsawg leeg kuj muaj xws li paraffin thiab cyclic hydrocarbons uas yog tau los ntawm cov roj thiab ozokerite.

Refined paraffin - dab tsi yog qhov no? Nws yog tsiag ntawv los ntawm cov nram qab no nta:

• tsis muaj kob khoom;
• greasy mus rau lub kov;
• ntxhiab;
• tsis muaj saj;
• nkag soluble nyob rau hauv ntxhia roj thiab organic kuab tshuaj;
• insoluble nyob rau hauv dej thiab haus dej cawv.

Tsis refined paraffin - yog ib yam khoom uas yog yus muaj los ntawm xim av los yog daj tinge thiab darkens lub teeb.

Qhov saum toj no cov ntaub ntawv uas muaj zoo kuj mus acids thiab bases, oxidants, alkali hlau thiab halogens.

hom paraffin

Cov khoom no yog muab faib mus rau hauv lub nram qab no waxes:

• Heev kev (qib A thiab B);
• Unrefined (matchbox);
• peeled engineering (qib D thiab E);
• kev kho mob.

Qhov tseem ceeb tshaj yam ntxwv ntawm paraffin - yog:

• melting point - 50 ° C (tsis txo);
• roj cov ntsiab lus - yam tsawg kawg 0.6% thiab ib tug tshaj plaws ntawm 2.3% (tsis muaj ntau dua).

Cov yam ntxwv ntawm txawv match paraffin. Nws muaj ib tug melting kub yuav tsum 42 degrees Celsius, tab sis nyob rau hauv txhua rooj plaub tsis qis, thiab cov roj cov ntsiab lus yuav tsis ntau tshaj li 5%.

Kev siv cov paraffin

Qhov saum toj no cov khoom yog dav siv nyob rau hauv cov nram no industries:

• printing;
• ntawv;
• textile;
• tawv;
• hluav taws xob;
• pleev xim.

Tsis tas li ntawd nws yog siv:

• rau paraffin nyob rau hauv cosmetology thiab tshuaj;
• raws li ciab rau taws tswm ciab;
• raws li ib tug roj nplua nyeem rau kev sib txhuam qhov chaw ua los ntawm cov ntoo;
• nyob rau hauv ua ke nrog nrog roj ua raws li ib tug corrosion resistant txheej;
• rau zus tau tej cov roj av jelly;
• Cov khoom no yog sau npe ua E905 - ib tug khoom noj khoom haus additive;
• Nws ua raws li ib tug roj nplua nyeem rau skiing snowboarding;
• siv nyob rau hauv lub kos duab thiab nuclear physics (neurons thiab slows ib tug "generator" protons).

Nyob rau hauv tas li ntawd, cov paraffin yog nquag siv nyob rau hauv electronics. Nws yog siv nyob rau hauv lub sij hawm uas qhov yuav tsum tau hluav taws xob siab zog, uas tsis muaj nqi, yam tsawg kawg nkaus AC poob thiab tau ceev kev tso tawm ntawm no yooj yim txoj kev ntawm cua sov rau cov sau.

Yuav ua li cas yog txawv los ntawm saum toj no-hais roj av ciab?

Lub ciab yog ib tug complex sib tov ntawm cov khoom esters tsim fatty acids thiab ntau dua alcohols (high molecular nyhav).

Yuav ua li cas yog qhov txawv ntawm qhov saum toj no tshuaj? Nws yuav tsum tau muab sau tseg tias cov khoom tsis hlawv kiag li, thiab tsuas yog melts - yog, ntawm chav kawm, cov ciab. Paraffin Conversely, siab noj.

Ciab yog txawv daj-xim av zas. Paraffin yog tsis tshua muaj dawb. Tag nrho lwm cov ntxoov manufacturers npaj los ntawm kev ntxiv lub dyes.

Ntuj ciab yog ib tug natural, environmentally phooj ywg tshuaj. Paraffin tau los ntawm cov roj av, li ntawd, nws yog ib tug hluavtaws cov ntaub ntawv uas.

Ciab muaj zog feem ntau tsa av nplaum. Nws yog saj zawg zog heev, heev mos mos, zas txaus. Paraffin, conversely, overly crumble thaum txiav.

Yuav ua li cas siv ciab nyob hauv tsev?

Cov khoom no yog kev koom siv rau paraffin. Qhov no yog ib tug heev thiab tej yam ntuj tso txoj kev, uas yuav muab ib lub sij hawm los mus tshem tawm cov tsis xws luag thiab tsis zoo ntawm daim tawv nqaij thiab tsis yog. paraffin txheej txheem yog raws li nyob rau kev siv ntawm lub aforementioned tshwj xeeb zaj duab xis khoom, uas tsim lub thiaj li hu ua tsev cog khoom nyhuv.

Paraffin nyob rau hauv lub tsev muaj peev xwm yuav siv tau rau:

• tshuaj dawb daim tawv nqaij;
• tshem lub thib ob lub puab tsaig thiab gravitational ptosis;
• Kev tiv thaiv ntawm daim tawv nqaij tiv thaiv tej kab nrib pleb thiab dryness;
• ntxuav ntawm daim tawv nqaij, nws rejuvenation.

Paraffin txhais tes nyob rau hauv tsev yuav ua li cas, ntawm chav kawm, yog yooj yim. Ua li no koj yuav tsum yuav lim kom hniav zoo nkauj paraffin. Kws txawj taw tes kom paub tias cov neeg uas ua xua yuav tau mus yuav cov khoom nrog rau cov ntsiab lus ntawm txiv duaj butter.

Paraffin yuav tsum tau rhuab mus rau ib tug kua hauv lub xeev. Rau lub hom phiaj no, cov dej da dej txoj kev. Ces nws yog ib qho tseem ceeb mus nqa tawm ib txhais tes zaws los yog ib tug siv cov nplauv thiab, piv txwv li, tshwj xeeb cov hnab looj tes. Tom ntej no, txo lub caj npab rau hauv cov kua paraffin thiab tam sim ntawd tshem tawm cov lawv. Tom qab 10 vib nas this, rov qab cov kauj ruam no. Peb yuav tsum tau nyob rau hauv ob txhais tes tsim nyias "hnab looj tes" los ntawm lub ciab. Ces ob txhais tes qhwv los yog lo zaj duab xis, e.g., ib lub hnab yas hnab txhuv thiab khaws cia rau tsawg kawg 20 feeb.

Tom qab hais tias, tshem tawm cov ciab. Re-siv cov khoom, kws txawj qhia tsis tau. Tom qab ntawm txoj kev ntawm tes yuav tsum tau thov cov qab zib rau moisturize ntawm daim tawv nqaij.

Paraffin - qhov no yog ib tug zoo cov khoom uas tau pom nws daim ntawv thov nyob rau hauv ntau yam teb.
