Ukukhetha i i-wax engcono yokulahleka kwefektri yokulahla i-wax imisebenzi ayikokufumana eyona ndlela inexabiso eliphantsi-imalunga nokuphelisa iintsilelo ezifihliweyo ngaphambi kokuba zifike kwiziko. Siye sabona imveliso emininzi kakhulu ibaleka kwinqanaba lokutshiswa ngenxa yentsalela yewax evala iipaseji ezilungileyo kwindawo yempompo ye-cobalt alloy. Abanye baye balahla i-30% yebhetshi emva kokuqhekeka kwegobolondo-balandelelwe emva kokunyuka okungahambelani kwe-thermal ngexesha lokukhupha. Ezi ayingomngcipheko wethiyori. Ziindleko zemihla ngemihla ngexesha, izinto eziphathekayo, kunye nokuthembela kwabathengi.
Kutheni iiWax eziMgangatho zisilela phantsi kweMfuno yeShishini
Iifektri ezininzi ziqala ngeewax zotyalo-mali oluqhelekileyo eziyilelwe ubucwebe okanye i-aluminiyam yoxinzelelo oluphantsi. Oko kuyasebenza-ude uqhube i-AMS 5387 imizimba ye-cobalt alloy alloy kwi-1,550 ° C okanye i-T800-based nozzles efuna ± 0.05 mm ulawulo lwe-dimensional kumacandelo e-0.8 mm eludongeni. Iiwax eziqhelekileyo azinazo iimpawu ezintathu ezingenakuxoxisana: ukutshiswa okuchanekileyo okungenathuthu ngaphantsi kwe-650 ° C, i-zero surface tack emva kokudilizwa, kunye nokuncipha kwe-thermal ngaphantsi kwe-0.45% ukusuka kwi-25 ° C ukuya kuma-60 ° C. Ngaphandle kwabo, ufumana iidiphozithi zekhabhoni ezonakalisa ukugqiba komphezulu, ukutsala komngundo okuphazamisa iiflange ezibhityileyo, okanye iintanda ezincinci kumaqokobhe eceramic ngexesha lokuthotywa komphunga.
Siye savavanya iiwax zemizi-mveliso ezisixhenxe kwiinyanga ezili-18—kubandakanywa nemixube emibini yobunikazi-kwiindawo zokwenyani zemveliso: izindlu zepiston pump cylinder, iivalve zoxinzelelo lwehydraulic, kunye newinch center shaft rollers. Bathathu kuphela abaphumelele ukuqinisekiswa komjikelo ogcweleyo. Umdlali obalaseleyo wayengeyona i-wax ephezulu yokunyibilika. Yayiyeyona inoluhlu oluncinci lokuqiniswa (52-54 ° C), i-viscosity ephantsi kwi-65 ° C (8,200 cP), kunye nentsalela yothuthu eqinisekisiweyo engaphantsi kwe-0.003% emva kwe-620 ° C / 2-iyure yokutshiswa kwi-ASTM F2897.
Iikhrayitheriya ezine zobuGcisa Akukho mzi-mveliso kufuneka utsibe
Ulibale amabango okuthengisa. Nantsi eyona nto ibalulekileyo xa ulungelelanisa i-wax yotyalo-mali olunentembeko ephezulu:
- Uzinzo lweDimensional emva kokutofa: I-Wax kufuneka ibambe ukunyamezela kwe-GD & T ngokupholisa-nakwiindawo ezilinganayo ezifana neziseko zempompo ezinobude obuyi-220 mm kunye nobukhulu bodonga lwe-3.2 mm. Silinganisa i-shrinkage kumanqaku amathathu: i-core, mid-wall, kunye ne-flange edge. Ukuphambuka okwamkelekileyo: ≤0.38% inguqu epheleleyo yomgca.
- Ukuhambelana newaxing: Ukukhutshwa komphunga kufuna ukunyibilika ngokukhawuleza, ngokupheleleyo ngaphandle kokudumba okanye ukudumba. Iiwax ezine->0.8% yasimahla yeeasidi ezinamafutha zibe ngugwebu phantsi komphunga ozeleyo—ubangela ukuba iqokobhe libe delamination. Ukudlula okuqinisekisiweyo: akukho ntsalela ebonakalayo kwi-3 mm iziteshi zokupholisa zangaphakathi emva kwe-12-minute 160 ° C umjikelo womphunga.
- Ulawulo lokuncamathela kwiqokobhe: Ukubambelela kakhulu kubangela ukuphuka kwegobolondo ngexesha lokuphatha. Okuncinci kakhulu kubangela ukuphakanyiswa kodaka. Amandla afanelekileyo kumphezulu we-wax: 34–36 mN/m ku-30°C—alinganiswa nge-contact angle goniometry, hayi uqikelelo lwedatha.
- Umda wokusebenziseka kwakhona: Iwax esetyenzisiweyo ithoba ngokukhawuleza kumaqhezu aguquguqukayo. Silandelela i-flash point drop kunye nenombolo ye-asidi yokunyuka. Umda wokusebenzisa kwakhona: max 3 imijikelo ukuba inani leasidi lihlala <0.8 mg KOH/g kunye ne-flash point ihlala i-≥110 °C.
Indlela QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Iqinisekisa ukusebenza kweWax
Kwiziko lethu elithobela i-ISO eQingdao, isiqinisekiso se-wax asingomsebenzi walebhu—lisango lokuvelisa. Yonke i-wax entsha ifumana iimvavanyo ezine ezifanayo:
- I-50-part trial run of the real customer part: AMS 5387 cobalt alloy plug nge-0.5 mm ukunyamezela kwe-radial kwi-12 mm OD.
- Ukulinganisa kwe-CMM kwangaphambili kunye ne-post-dewaxing ukulinganisa ukuchithwa kwepateni.
- Uhlalutyo lwe-Thermogravimetric (TGA) yentsalela yokutshiswa kwi-substrates yensimbi engenasici-eqinisekisiweyo ngokuchasene ne-SEM-EDS i-mapping elemental mapping.
- Ukuguga okukhawulezileyo: iiyure ezingama-72 kwi-40 ° C / 85% RH, ilandelwa ngamandla okuqina kunye novavanyo lokwandisa nge-ASTM D638.
Le nkqubo ibambe i-wax enye edibene nawo onke amaphepha-kodwa ayiphumelelanga uvavanyo #2. I-coefficient yayo yokwandiswa kwe-thermal inyuke ngaphezu kwe-85 ° C, ibangela i-0.12 mm offset kwigxalaba elibalulekileyo lokutywina. Loo nxalenye yayiza kudlula kuhlolisiso olubonakalayo kodwa yavuza kwiibhari ezingama-350 kwinkonzo yasentsimini. Asizithumeli iingqikelelo. Sithumela idatha.
Ukukhetha i-wax yakho: Amanyathelo alandelayo anokuSebenza
Musa ukuxhomekeka kwiisampulu zomthengisi yedwa. Qhuba olu luhlu lokukhangela phambi kokuba ugqibezele olwakho i-wax engcono yokulahleka kwefektri yokulahla i-wax ukhetho:
- Cela iigophe ezipheleleyo zeTGA—hayi nje amabango “angenathuthu”. Ubunzima bentsalela yemfuno % kuma-550°C, 600°C, kunye nama-650°C.
- Vavanya i-dewaxing kwinkqubo yakho yeqokobhe ngqo: isibophelelo esifanayo, istucco esifanayo, ishedyuli efanayo yokomisa. I-wax egqibeleleyo ye-silica sol shells inokusilela kwintlekele nge-colloidal zircon.
- Qinisekisa iiparamitha zenaliti koomatshini bakho: ubushushu bombhobho, ukuzalisa isantya, uxinzelelo lwepakethe. Ukutshintsha kwe-2°C kwiqondo lobushushu lokunyibilika kunokuguqula uburhabaxa bomphezulu i-Ra nge-0.4 µm—yanele ukuchaphazela ukumanzisa okuludaka lwe-ceramic.
- Funa ukulandeleka kwebhetshi: inombolo yeqashiso, izatifikethi zemathiriyeli ekrwada, kunye neengxelo ze-QC ezihambelana neodolo yakho yokuthenga. Akukho ngaphandle.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imithombo yewax eqinisekisiweyo edibana nale miqobo yemveliso yayo-kwaye yabelana ngeprotocol yokuqinisekisa ngokupheleleyo kunye namaqabane afanelekileyo. Ngenxa yokuba ukusebenza kwe-wax engaguqukiyo akuloziko leendleko. Ngumaleko wokuqala wengqibelelo yomgangatho kuyo yonke ivalve yoxinzelelo, yonke indlu yempompo, yonke i-cobalt alloy icandelo elakhelwe ukusinda kuxinzelelo lwehlabathi lokwenyani.
Jonga ngaphaya kwendawo yokunyibilika. Ukulinganisa ukucutheka. Khangela intsalela. Qinisekisa kwijometri yakho. Yiloo ndlela uyeka ngayo ukuleqa iziphene-kwaye uqalise ukuthumela iinxalenye ezisebenzayo.
