Ua cov txheej txheem loj hlob ntawm cov hlau
Peb yog Quzhou Chengji Txheej los ntawm Zhejiang, Suav. Rau cov khoom no, peb tsom rau ib qho txiaj ntsig tseem ceeb: adhesion siab. Nws yog tsim los daws qhov teeb meem ntawm txheej txheej txheej. Qhov no tshwm sim los ntawm pob, cuam tshuam, lossis kev hloov hauv ib puag ncig. Vim li cas qhov no tseem ceeb heev? Adhesion yog lub hauv paus rau tag nrho lwm yam khoom. Yog tias adhesion tsis zoo, kev tiv thaiv xeb zoo tsis muaj teeb meem. Yog tias cov xim poob tawm, muaj dab tsi los tiv thaiv? Peb siv chemistry los ua cov txheej txheem kom muaj zog rau cov hlau. Peb siv molecular tsim thiab interface science. Qhov adhesion peb tau txais yog qhov zoo tshaj plaws hauv kev lag luam. Txawm hais tias nws yog stainless hlau du los yog tawv - mus rau - nplaum galvanized steel, cov txheej no tuav nruj.
Peb Txoj Kev Tuav
Peb hu cov thev naus laus zis hauv qab no "ntau-anchoring." Peb siv peb lub zog ua ke los tuav lub txheej.
Ua ntej, peb muab ntau pawg polar nyob rau hauv cov resin. Cov no zoo li cov hooks me. Lawv tsim cov tshuaj bonds nrog cov hlau nto. Peb hu qhov no "chemical anchoring."
Qhov thib ob, peb ntxiv ib tus neeg sawv cev tshwj xeeb silane. Qhov no ua zoo li tus choj molecular. Ib kawg txuas rau cov hlau. Lwm qhov kawg txuas rau cov resin. Peb hu qhov no "coupling anchoring."
Thib peb, peb tswj cov particle loj. Cov me me tuaj yeem nkag mus rau hauv cov pores me me ntawm cov hlau. Tom qab ci, lawv zoo li tsob ntoo hauv paus hauv av. Peb hu qhov no "mechanical anchoring."
Thaum lub sijhawm tsim khoom, peb siv lub tshuab tshwj xeeb hu uaXPStxhawm rau txheeb xyuas daim ntawv cog lus tshuaj ntawm lub interface. Qhov no ua kom txhua batch muaj kev ruaj khov rau cov hlau.
Cov ntaub ntawv uas thawb cov txwv
Peb cov ntaub ntawv adhesion yog ntau dua li cov qauv qub. On du304 stainless hlau, tus ntoo khaub lig- txiav kev xeem muab qhov zoo tshaj plaws0- qib. Peb txiav ib daim phiaj thiab rub nws nrog daim kab xev. Tsis muaj squares tawm. Hauv kev rub tawm - tawm kev xeem ntawm carbon steel, tus nqi dhau lawm15 MPa. Txhawm rau muab koj lub tswv yim, lub zog rub lub pobzeb ceramic rau ntawm phab ntsa tsuas yog 2-3 MPa. Qhov tseem ceeb tshaj, qhov ua tsis tiav yog feem ntau100% cohesive. Qhov no txhais tau tias qhov tawg tshwm sim hauv cov txheej txheem, tsis yog nruab nrab ntawm cov txheej txheem thiab cov hlau. Daim ntawv cog lus muaj zog heev uas lub txheej yuav zoo dua rhuav nws tus kheej dua li tso cov hlau mus. Peb kuj ua qhov ntsuas thermal shock. Peb lub voj voog ntawm-40℃rau +80℃rau 10 cycles. Tom qab no, qhov adhesion tseem dhau lawm95%.

Kev ua tau zoo nyob rau hauv cov xwm txheej nyuaj
Ua kom adhesion nyob rau hauv qhov hnyav hnyav yog qhov tseem ceeb dua. Peb tau ua ntau qhov kev sim siab heev. Tom qab ib tug humidity xeem rau1000 teev, adhesion yog tib yam. Tom qab500 teevNyob rau hauv ntsev tsuag, qhov adhesion ntawm khawb yog tseem zoo. Tom qab adej boil rau 2 teev, zaj duab xis tsis muaj npuas thiab tsis tev. Tus ntoo khaub lig- txiav adhesion tseem yog qhov zoo tshaj plaws0- qib. Ib tus neeg siv khoom ua dej rhaub dej tank. Cov txheej txheem yuav tsum dhau qhov kev sim ntsuas dej. Lawv sim ntau tus neeg xa khoom. Cov txheej yog bubbled los yog poob adhesion. Nrog peb cov khoom, lawv kis tau yooj yim. Qhov kev ua yeeb yam no zoo meej rauqhov chaw hauv qhov chaw kub, ntub dejzoo li lub tshuab rhaub dej, lub tshuab hluav taws xob, thiab cov tshuab ntxuav tais diav.
Kev tiv thaiv xeb zoo dua nrog tsawg xim
Zoo adhesion ua ntau dua li tuav cov xim. Nws kuj txhim kho kev tiv thaiv xeb. Ib txheej uas nplaum zoo thaiv dej thiab oxygen los ntawm kev txav mus rau sab hauv qab zaj duab xis. Txawm hais tias cov yeeb yaj kiab raug khawb, qhov corrosion yog txwv rau thaj tsam me me. Ib tus neeg xav tau720h uantawm ntsev tsuag kuj. Ib yam khoom tsim nyog a25 micronzaj duab xis. Nrog peb cov khoom, vim tias cov adhesion zoo heev, lawv tsuas yog xav tau18-20 microns. Qhov no txhais tau tiaslawv siv 20% tsawg dua xim. Lub sij hawm tso nyiaj tau luv dua. Qhov no txhim kho lawv cov kev tsim khoom ceev. Qhov no yog qhov txiaj ntsig ntxiv ntawm adhesion siab. Koj tau txaisCov nqi qis dua, kev ua haujlwm siab dua, thiab kev siv tshuab zoo dua txhua lub sijhawm.
