Kanema wophatikizika wa pulasitiki ndi zinthu zambiri zogwiritsidwa ntchito pazomwe mungagwiritse ntchito. Kubwezeretsa ndi kutentha komaliza ndi njira yofunika kwambiri yoperekera chakudya chakutentha kwambiri. Komabe, zinthu zakuthupi za mafilimu ophatikizika zimakonda kuwonongeka kwa mafuta pambuyo potenthetsedwa, zomwe zimapangitsa kuti pakhale zinthu zosavomerezeka. Nkhaniyi ikusambiranso mavuto wamba ataphika matumba otentha kwambiri, ndikuyambitsa njira zawo zoyeserera zoyeserera, ndikuyembekeza kukhala ndi malangizo ofunikira pakupanga zenizeni.
Kutulutsa kwa kutentha kwambiri kumayambitsa mawonekedwe omwe amapezeka kawirikawiri amagwiritsidwa ntchito ngati nyama, zinthu zopangidwa ndi soya komanso zina zokonzekera chakudya. Nthawi zambiri zimakhala zopanda pake ndipo zimatha kusungidwa kutentha pambuyo potenthedwa komanso kuwikiridwa kutentha kwambiri (100 ~ 135 ° C). Chakudya chonyamula katundu chosavuta ndi chosavuta kunyamula, chokonzeka kudya mutatsegula thumba, ukhondo komanso losavuta, ndipo limatha kusamaliranso chakudyacho, motero amakondedwa kwambiri ndi ogula. Kutengera ndi njira yodulira ndi ma Pactagrang zida, alumali moyo wa report-phukusi lazakudya kuyambira theka chaka ndi zaka ziwiri.
Njira yotsatsira chakudya chambiri ndi chopanga thumba, yokuluka, kuthirira, kusindikizidwa, kuphika ndi kuzizira komanso kuzizira, ndi kuziziritsa, ndi kuziziritsa, ndi kuziziritsa. Kuphika ndi kutentha kutsitsa ndi njira yoyambira njira yonseyo. Komabe, mukamapanga matumba opangidwa ndi zidutswa za polimar - ma pyaclal, mayendedwe a telecular amalima atatenthedwa, ndipo zinthu zakuthupi za zinthuzo zimakonda kuthira mafuta. Nkhaniyi ikusambitsa mavuto wamba ataphika matumba owotcha kutentha, ndikuyambitsa njira zawo zoyeserera.
1. Kusanthula kwa mavuto wamba okhala ndi matumba osakanikirana
Chakudya chamanthedwe kwambiri chimakonzedwa ndipo kenako chimatenthetsedwa ndikumatsirizika limodzi ndi zida zapamalo. Kuti mukwaniritse zinthu zapamwamba komanso zotchinga zabwino, zolemba zoletsa, zimapangidwa ndi zida zosiyanasiyana. Zipangizo zomwe anthu ambiri amagwiritsa ntchito zimaphatikizanso pa, Pet, Al ndi CPP. Zojambula zambiri zogwiritsidwa ntchito zimakhala ndi zigawo ziwiri za mafilimu ophatikizika, ndi zitsanzo zotsatirazi (Bopa / CP / CP / CPP). Mukupanga, zovuta zofala kwambiri ndizo makwinya, matumba osweka, kutulutsa mpweya ndi fungo mutaphika:
1). Pali mitundu itatu ya makwinda atatu okutira m'matumba: zopingasa kapena zowongoka kapena zowongoka pazinthu zapansi panthaka; makwinya ndi ming'alu pamtundu uliwonse wosanjikiza komanso wosauka; Shrinkage ya phukusi la maziko, ndipo shrinkage ya wosanjikiza ndi zigawo zina zophatikizika, zotsekeredwa. Matumba osweka amagawidwa m'mitundu iwiri: kusuntha molunjika ndi kukwinda kenako kuphulika.
2) .Delamination ikunena za zodabwitsazi kuti zigawo zophatikizira za zida za ma dleaging zidasiyanitsidwa ndi wina ndi mnzake. Kuchepetsa pang'ono kumawonekera ngati mabatani opsinjika pazigawo zopsinjika kwa ma Cell, ndipo mphamvu zosenda zimachepetsedwa, ndipo zimatha kukhala ndi nkhawa. Zovuta kwambiri, zomwe zimapangidwira mtundu wophatikizika zimalekanitsidwa m'dera lalikulu mukaphika. Ngati kuchepetsedwa kumachitika, kulimbikitsa kolimbitsa thupi pakati pa zigawo za malo ophatikizika kumatha, ndipo katundu wathupi ndi chotchinga chimatha kukwaniritsa zofuna za moyo, nthawi zambiri zimapangitsa kuti pakhale bizinesi.
3). Panthawi yofananira ndi nthawi yosungirako zinthu zachilengedwe, kuchuluka kwa malonda kumachepa ndipo mpweya woonekeratu umapezeka mu ma CD. Chifukwa chake, vuto lakhalidwe labwino limaphatikizapo zinthu zambiri. Zogulitsa zimakhudza kwambiri. Kupezeka kwa kutaya kwa mpweya kumagwirizana kwambiri ndi kusindikiza kwa kutentha ndi kusanja kosakanikirana kwa thumba la rector.
4). Fungo lophikira limakhalanso vuto labwino kwambiri. Thuma lachilendo lomwe limawonekera pambuyo pophika limakhudzana ndi zotsalira zosungunulira kwambiri pakupanga zida za phukusi kapena kusankha zinthu mosayenera. Ngati kanema wagwiritsidwa ntchito ngati kusindikiza kwapakati wamtundu wamatumba otentha kwambiri kuposa 120 °, filimuyo imakonda kununkhira pamtenthedwe kwambiri. Chifukwa chake, RCPP imasankhidwa nthawi zambiri ngati mkati mwa matumba ophika kwambiri.
2. Njira zoyesera zamagetsi zam'madzi zotsutsana
Zinthu zomwe zimayambitsa mavuto amtundu wa revortor-contraging ndizovuta ndipo zimaphatikizapo zinthu zambiri monga zopangira zophatikizika, zomata, zikwangwani, ndi thumba zimawongolera njira. Pofuna kuonetsetsa kuti phukusi ndi chakudya cha alumali, ndikofunikira kuchititsa makonda ophikira pazinthu zomwe zili ndi zida.
Matumba a National Kugwiritsa Ntchito Matumba a Paketi ndi GB / T10004-2008 "Pulogalamu Yowuma" GB / T10005-1998999999999 GB / T 10004-2008 imaphatikizapo zinthu zosiyanasiyana zakuthupi ndi zosungunulira zosungunulira ndi matumba osakanikirana, ndipo zimafunikira kuti matumba osalimbana ndi makompyuta amayesedwa kwambiri. Njirayo ndikudzaza matumba osakanikirana ndi 4% acetic acid, 1% sodium sulfide, 5% sodium chloride ndi mafuta a masamba, ndikuwotcha mu mphindi 40, ndikuzizira pomwe kupsinjika sikunasinthe. Kenako mawonekedwe ake, mphamvu yayikulu, yokwezeka, yolunjika ndi kutentha mphamvu zokukizira zimayesedwa, ndipo kukula kwake kuli poyesa kuwunika. Fomu ili motere:
R = (AB) / a × 100
Mu fomula, R ndi kuchuluka kwa zinthu zoyesedwa, ndi mtengo wapakatikati pa mayeso oyeserera asanachitike kutentha; B ndi mtengo wapakatikati pazinthu zoyesedwa pambuyo poyeserera kwapamwamba kwambiri. Zofunikira zomwe zikuchitika ndi: "Pambuyo pa mayeso ozizira kwambiri, zopangidwa ndi kutentha kwa 80 c kapena pamwamba pa thumba, ndikuchepetsa mphamvu yopumira mkati kapena kutentha. Mlingo uyenera kukhala ≤30%".
3. Kuyesa kwa zinthu zakuthupi zam'matumba osakanikirana
Kuyesa kwenikweni pa makinawo kungazindikire bwino momwe amagwirira ntchito poyambira. Komabe, njirayi sikuti imangowononga nthawi, komanso yocheperako kupanga ndi chiwerengero cha mayesero. Imakhala ndi mwayi wosagwiritsa ntchito bwino, zinyalala zazikulu, komanso mtengo wokwera. Kudzera muyeso wa retroction kuti muzindikire katundu wowoneka bwino ngati katundu, peel Run, Hearn Chikumbutso chisanachitike ndipo mutatha kungobwezera, kukhazikika kwa chikwama cha rector chitha kuweruzidwa. Mayeso ophikira nthawi zambiri amagwiritsa ntchito mitundu iwiri mwazinthu zomwe zilipo. Kuyesa kophika pogwiritsa ntchito zomwe zili mu zomwe zingatheke pafupi ndi momwe mungathere kuti mupangitse kuti pakhale momwe mungapangire bwino kuti mulowetse mzere wopangidwa ndi ma batchi. Poyendetsa mafakitale, simulants amagwiritsidwa ntchito poyesa kukana zinthu zomwe zatsamba zomwe amapanga komanso musanasungidwe. Kuyesa kuphika magwiridwe ophika ndikothandiza komanso othandiza. Wolemba amafalitsa njira yoyesera yoyeserera yogwiritsira ntchito ma comtort-osagwirizana ndi kuwaza ndi chakudya chakumwa kuchokera kwa opanga atatu opanga ndikuyendetsa mayesero owiritsa. Njira yoyeserera ili motere:
1). Mayeso ophikira
Zida: Zotetezeka komanso zanzeru - kutentha kwambiri kuphika mphika, HST-H3 Chisindikizo cha Senger
Njira Zoyeserera: Ikani mosamala 4% acetic acid m'thumba la 1% kuchokera kuwiri la magawo awiri mwa atatu a buku. Musamale kuti musayipitse Chisindikizo, kuti musakhudze kukoma. Mukadzaza, kusindikiza matumba ophika ndi HSt-H3, ndikukonzekera zitsanzo zonse 12. Kusindikizidwa, mlengalenga mu thumba kuyenera kutopa kwambiri momwe mungathere kuti ateteze mpweya wophikira ku kuphika zotsatira zoyeserera.
Ikani zitsanzo zosindikizidwa mumphika wophika kuti muyambe mayeso. Khazikitsani kutentha kophika mpaka 121 ° C, nthawi yophika mpaka mphindi 40, Steanthee 6, ndi wiritsani 6 zitsanzo. Pa mayeso ophikira, samalani kwambiri chifukwa cha kusintha kwa mpweya kuthamanga ndi kutentha mu mphika wophika kuti muwonetsetse kuti kutentha ndi kukakamizidwa kumasungidwa mkati mwake.
Kuyesedwaku kumamalizidwa, ozizira mpaka kutentha, uchotse ngati pali matumba osweka, malo a 1 # ndi 2 # atakhala osalala. Pamwamba pa kambuku 3 # sanali yosalala kwambiri mukaphika, ndipo m'mphepete mwake munakhazikika kulowetsa.
2). Kufanizira kwa katundu
