The degrease pamwamba? Degreaser magalimoto

Nthawi pali kufunika amawakhula aliwonse banga padziko thupi galimoto. Mu zikhalidwe mzinda izo zikhoza kuchitidwa kokha pa galimoto wosambitsa. Komabe, ambiri a degreasing chofunika pamene penti galimoto. Kodi kuchita? Kudzera ndondomeko ofanana amapereka lumikiza wabwino ndi pamwamba thupi utoto. Kodi ndi mmene degrease, muyenera kusankha isanayambe ntchito. Dziwani kuti njira mwachizolowezi zolinga zimenezi si nthawi yabwino. Komanso, pamwamba chithandizo nyimbo m'pofunika kuganizira ena mokoma lapansi. Chotero kodi degrease pamwamba?

Kodi imeneyi

, M'pofunikanso tipeze chifukwa chake ichi ndikofunikira pamaso inu funso, kodi degrease pamwamba pamaso kupenta. Childs, zitsulo amaliona ndi mankhwala umenewu posungitsa guluu wolimba yachibadwa zakuthupi imene thupi ndi refinishing. Nthawi zina kuli kofunikira. Pa nthawi imene galimoto kwathunthu repainted, thupi ayenera yokutidwa ndi wosanjikiza phunziroli wapadera. Kuonetsetsa guluu wolimba zabwino, amafuna degreasing.

Guluu wolimba Ndipotu - zowalamulira zakuthupi wina ndi mzake. Izi zonse zimachitika pa mlingo maselo. Ngati chitsulo kapena pakati pa phunziroli ndi ❖ kuyanika utoto adzakhala wosanjikiza mafuta, guluu wolimba awo ndi zoperewera. Izi zikhoza kenako bwanji maonekedwe a galimoto. Kuchokera kulikonse kugwedera utoto pang'onopang'ono kuguluka.

Kodi worsens guluu wolimba ndi

Degreaser magalimoto osati amachotsa mafuta. Uve, zosiyanasiyana organic, wochuluka zinthu chiyambi achilengedwe, ndi zina zotero - zonsezi amachepetsa guluu wolimba zipangizo pa mlingo maselo. Komanso, guluu wolimba amakhudza okusayidi woonda filimu. Izo zikuwoneka ngati pang'ono dzimbiri filimu padziko thupi. filimuyi analimbikitsanso kuchotsa. Ngati inu kuchotsa zolengeza kwathunthu sichitha, m'pofunika kutembenukira mu khola mankhwala pawiri kuti kodi sudzalepheretsa zitsulo guluu wolimba ndi utoto pa mlingo maselo.

The degrease pamwamba pamaso gluing kapena kupenta

Nthawi zambiri, "mzimu woyera" ntchito zochizira thupi. Komabe, ambiri amasokoneza ndi njira mwachizolowezi ya palafini kapena mafuta dizilo, ngati iwo ali pafupifupi fungo chomwecho. Kusiyana pakati pa zinthu izi ndi yaing'ono. Onse mankhwala ndi osakaniza chakudya. Yopangidwa madzi ofanana ndi tuzigawo twa distillation.

Ena maumboni amasonyeza kuti "mzimu woyera" - mawonekedwe ofatsa a palafini. Dziwani kuti pamalowo ndi bwino amasungunula mafuta, phula, kapena yamawangamawanga jombo ndi utomoni wonunkhira. Mosiyana palafini, "White Mzimu" mosavuta anatsuka kutali ndi galimoto madzi opanda. Onse mankhwala ali oyenera pamalo degreasing. The "White Mzimu" - pawiri kuwala umene pang'ono vaporized ndi yotsala ya njira sikukuvulaza ❖ kuyanika pambuyo kupenta.

Ndiyenera ntchito palafini

Degreasing - ndi njira zophweka kuti zikhoza kuchitika kunyumba. Chinthu chachikulu - kusankha chida choyenera. Ena akatswiri okwerera kusamba ntchito palafini chifukwa ntchito zipangizo zina zapadera kusamalira thupi. Zimenezi zimathandiza kuti achotse kwathunthu mankhwala kuchokera pamwamba, kusiya fungo lake. Ngati degreasing magalimoto ikuchitika garaja, pakuti zolinga zimenezi akulimbikitsidwa kugwiritsa ntchito "mzimu woyera" kapena ndalama ofotokoza. Ndi bwino kugula mankhwala amene akhala hydrotreated. Pa mlingo uwu, muyenera kulipira mwapadera, makamaka ngati thunthu amapangidwa domestically.

Kodi ntchito osavomerezeka

Kodi degrease padziko, ndi kuti sitiyenera ntchito? Ing'ono nkhabe kulengeza ntchito dizilo, petulo ndi dizilo. Kumene, iwo ali bwino degreased. Komabe, zinthu zina zingasokoneze.

CHENJEZO ayenera kugwiritsa ntchito nambala solvents ngati №645, №646 ndi zina zotero, ndi kafungo kabwino. zomangira ndi mosavuta kusungunuka osati organic, dothi ndi mafuta, komanso zokutira. Chithandizo cha thupi amaloledwa ndi solvents acetone kusanachitike filler.

Ngati palibe njira iliyonse yapadera, n'zotheka ntchito wamba viniga njira, wothira madontho ochepa a detergent kwa tableware.

Kuti ntchito fakitale

Fakitale ntchito ndi sodium carbonate njira (35-50 g / L) kapena ndi sodium hydroxide njira (90-150 g / l). Izi degreaser magalimoto ayenera kugwiritsidwa ntchito mosamala kwambiri. Asanayambe ntchito, Ndi bwino kuvala magolovesi pamene ndi sodium palokha ndi zikuwononga kwambiri. The njira akhoza osati kuchotsa mafuta padziko thupi, komanso kudya mu khungu pa manja.

Komanso njira zamchere sangathe kuchotsa kwathunthu Madontho a mafuta ndi mafuta unakhuthala. Nyimbo oterowo otsika detergency. Ntchito soda analimbikitsa pokhapokha Kutentha 90 ° C. Inu simungakhoze kubweretsa kwa chithupsa. Tikumbukenso kuti njira acidic bwino anachotsa filimu okusayidi, koma bwino rinsed mafuta. Chotero kodi bwino degrease pamwamba pa thupi?

trichlorethylene

Nthawi zina, chifukwa kudziyeretsa thupi ntchito trichlorethylene kapena zinthu naye iye mu masanjidwe lapansi. Komabe, nthumwi izi ndi zovuta. Iwo sangakhoze lingagwiritsidwe zotayidwa. Kupanga trichlorethylene ntchito okha degreasing zitsulo akakhala.

Pa kukhudzana ndi zotayidwa wa thunthu zikhoza inaphulika. Amagwiritsidwanso osavomerezeka kusakaniza madzi ndi trichlorethylene, kuyambira zomatira amayamba ndi aliuma misa. Nthawi zambiri mankhwala si ntchito mu mawonekedwe choyera mu mawonekedwe a emulsions. The degrease pamwamba, m'pofunika kudziwa pasadakhale kuti winanso kuwononga galimoto thupi.

Kukonza mu magawo angapo

Ngati inu simukudziwa momwe ndi zimene degrease pamwamba, n'zotheka amanena kuti akatswiri. Mu fakitale, kuyeretsa ikuchitika mu magawo angapo. Pamene izi zimachitika tsiku loyamba defatting sitepe. Kuyamba ndi pamwamba pa thupi ankachitira ndi "mzimu woyera". Ngati zitsulo ndi m'madera ena chidwi ndi dzimbiri, Ndi bwino kuyeretsa ndi osakaniza mowa ndi asidi phosphoric. Choncho ndikofunikira kusunga kuchuluka kwa zinthu:

1. Phosphoric asidi + madzi 1 5. njira ayenera kukhala ku 65 75%.
2. Isopropyl mowa - kuchokera 13 mpaka 18%.
3. Ethyl mowa - 10 14%.
4. The emulsifier uthenga ulalikidwa-7 - 0.5%.
5. Nitrobenzene - 0.1%.

Kuti njira ngati kunyumba ndi zovuta. Komabe, zamakono amalola opanga ambiri kutulutsa kalasi ina ya okonza. Mosavuta ntchito kunyumba. gulu ili la zinthu otchedwa antisilikony. Amavomereza ambiri ntchito zawo n'zosathekadi, monga aliyense ali katundu madzi. Tikumbukenso kuti antisilikony ambiri osakaniza mankhwala angapo organic omwe otsika kawopsedwe. Iwo akhoza kugwiritsidwa ntchito popanda kuopa mavuto thanzi. Komabe, thupi pamwamba isanafike kupenta bwino kuchotsa zotsala awo.

ayamikira

Tsopano inu mukudziwa zoti degrease pamwamba. Musanagule ndalama wapadera ayenera kuganizira ena mokoma lapansi. Ngakhale ntchito formulations sanali woopsawo tikulimbikitsidwa kuvala magolovesi ndi chigoba masking.

Kuchita degreasing ndondomeko zofunika ntchito matawulo awiri: mmodzi ndi chofunika kuti ntchito zikuchokera, ndipo chachiwiri - kuchotsa zatsalira.

Chithandizo ayenera kuchitika pambuyo sanding ndi kusanachitike kupenta. Mbali zopangidwa zotayidwa, m'pofunika kupereka chisamaliro chapadera. Osati zinthu zonse abwino zitsulo. Ikani inki zikuchokera molunjika padziko degreased ali osavomerezeka, chifukwa thupi liri ndi kulimbitsa kwa firiji.
