Kuzindikira kosasunthika kwa okhazikika (vocs) ndi chinthu chovuta kwambiri muzowunikira zachilengedwe, zaukhondo wa mafakitale, komanso thanzi komanso chitetezo. Zambiri za kuchuluka kwa ma voc otsika kwambiri monga Benzene, Toline, ndi Xynene adalimbikitsa mwachindunji zisankho zowonongeka ndi zoyeserera zaumoyo. Komabe, kusindikizidwa kokwanira panthawi yachitsanzo, kusungirako, ndi mayendedwe kumatha kubweretsa zotayika za votis, zomwe zimapangitsa kupatuka kapena zotsatira zosavomerezeka. Zosavuta kusindikiza za Mbale Zachikhalidwe - Mbale za Cap-Cap asanduke mabotolo ofunikira. Kodi maluso osindikizira angalimbikitsidwe bwanji? Nkhaniyi imayang'anira kusanthula kwakuya komwe kungachitike.

I. Kulephera kofala

Zoperewera za zipolopolo zachikhalidwe

Mbale zapansi-kapu zimadalira kwambiri pamanja, zomwe zimayambitsa kupsinjika. Kusasinthasintha kusintha kwa kutentha kumatha kuyambitsa kukula kwa mafuta komanso kuphatikizira, kumapangitsa kuti tizilombo toyambitsa matenda.

Mavuto obwera oyenda-otsika

Mankhwala otsika-oundana-poing-potchene otaya (owotcha <150 ° C) amatha kukhala omasuka msanga kutentha. Ngati gasket ya hical yabial ili ndi Adsorption yapamwamba kapena yolimbana ndi mankhwala, kutaya kwachitsanzo kumachulukitsa, kuthetseratu mitengo yobwezeretsa yoposa 30%.

Kuyipitsidwa ndi zolakwika

Kulawa sikungoyambitsa chidwi cha chandamale koma kungayambitsenso zovuta zakunja. Mwachitsanzo, kugwedezeka pamayendedwe kungamasulire zisoti zamitengo, zomwe zimapangitsa kuti zisaipidwe pakati pa zitsanzo zoyandikana ndi zowunikira za GC-MS.

Ii. Mayankho atatu aukadaulo okulitsa kusindikiza

Yankho 1:Pre-slit ptfe \ / silika wophatikizira septa
Ubwino Waukadaulo:
PTF (Polytetrafluoroenee) amapereka chisamaliro champhamvu, kupewa mawu a Adsorption.
Siketi ya silicone imapereka zotupa, kutentha kumakhala kosiyanasiyana.

Kapangidwe kakang'ono kokha kumachepetsa chiopsezo cha tinthu tating'onoting'ono pa nthawi ya singano.

Zojambula zogwiritsidwa ntchito: Kusanthula kwa VACs monga pa EPA 8260, HJ 644-2013, ndi mikhalidwe yofananayo.

Kuyankha 2: Openga Olamulira

Mtengo Wofunika:
- Kuwongolera konzekerani kusindikizidwa (kolimbikitsidwa kuti:
- Imatsimikizira kulumikizana pakati pa kapu ndi gasket, kupewa kutaya pakapita nthawi yosungirako.

Yankho 3:Mbale zamtunduwu zimagwirizana ndi miyezo ya EPA 8260

Njira Zosankhidwa:
- Kusasinthika kwamphamvu pakamwa pakamwa (E.g.,40ml mkamwa).
- Zida zagalasi ziyenera kukhala asidi ndi alkali-osagwira ndi leacality wotsika.
- Ndi limodzi ndi Rebta yotsimikizika, yotsimikizika kudzera mu kuyesa kopanda pake.

Iii. Phunziro la Mlandu: Kukonzekera Kukonzekera Kulondola pa Zowunikira

Labotale yoyesa zachilengedwe poyerekeza zomwe zikuchitika pakati pa mipanda yokhazikika ya Cap-Cap ndi mayankho omwe akonzedwe:

Zowunikira metric	Mbale zam'manja	PTFF \ / SICONE SEPA + HORQURROR
Mlingo wa BNZEne	68%	98%
Xylene rssd (%)	15.2	4.7
Mtengo wotulutsa	22%	0%

Kafukufukuyu adawonetsa kuti kukhazikitsa gawo lophatikizika ndi kuwunikira kwambiri kwa ma vacs otsika kwambiri (<1ppb) zowunikira, kugwirizanitsa deta \ / iec.

Iv. Pomaliza ndi Malangizo

Chisindikizo cha Kulephera mu zitsanzo za ma supps sizachilendo - zimakhudza mwachindunji kuvomerezeka ndi kukhulupirika kwa sayansi za malipoti owunikira. Laboratories ayenera:

Cholinga Chosakanikirana Kwambiri: Sankhani ptfe otsimikizika PTFF \ / SICONE SEPTA ndi Mbale Zosiyanasiyana Pakamwa.
Sinthani njira zosindikizira: Gwiritsani ntchito akatswiri othamanga oyendetsedwa ndi zodzikongoletsa pafupipafupi.
Kupititsa patsogolo kuwongolera kwapadera: kuwunikira kusindikizidwa kukhazikika kudutsa kuyesa kwa kubwezeretsa ndikusintha kwa azaka zokalamba.

Maganizo Amtsogolo: Kuchulukitsa Kwambiri Monga Mapulogalamu a EPA mpaka 17 chifukwa cha matchulidwe anzeru anzeru, kukhazikitsidwa kwa zida zokopa zanzeru komanso njira zodzipangira zokhazokha zidzasandukidwe njira yatsopano ya makampani.
