UFR-4 I-Epoxy yeBhodi yeBhodi yeBhodi
Fr-4 i-epoxy yeglasi yeglasi yemveliso yemveliso yemveliso yomgangatho kunye nokulungiswa
1. Emva kokuba umphezulu wobhedu sele udlalwa kwaye umelwe ukuba enze isekethe, ukuphatha kunye nokunxibelelana ne-PTFE Porto kufuneka incitshiswe. Umqhubi kufuneka athwale iigloves ezicocekileyo kwaye abeke ifilimu yebakwenzelwe ibhodi nganye yokutshintshelwa kwinkqubo elandelayo.
I-2. Indawo ye-ptfe ye-ptfeed irhabaxa ngokwaneleyo ukuba ingonwabisi. Kucetyiswa ukuba umgangatho we-plfe thaphathwa ukuba anikezele ngendlela eyaneleyo apho amaphepha athanjisiweyo okanye apho amajeli angatyhilekanga aya kudilika. I-chemistry esetyenziselwa inkqubo yokulungiselela i-PT inokusetyenziselwa ukulungiselela umphezulu. I-Plasma etking okanye i-sodium-enee-smistries ezifana neFliroetch® ngu-Actotch, iTetraetch® nguGore, kunye ne-Bop-Pr PrG® ye-APC iyacetyiswa. Iindlela ezithile zokulungisa ziyafumaneka kwakhona kumthengisi.
I-3. Unyango lobhedu lwecala kufuneka luqinisekise amandla e-quago. Ukugqitywa kwesekethe i-monoxide ye-monoxide kuya kuphucula ubume bomphezulu wokuxhotyiswa kwamachiza kunye nabanamakhwenkwe. Le nkqubo ifuna ukucoca ukususa intsalela kunye nee-oils zokulungisa. Emva koko, i-etching ye-etchipper yenziwa ukwenza indawo yeyunifomu. I-Brown Oxdide Inaliti ye-Crystals inza uzinzise ungqimba lwenkqubo yesaphulelo. Njengayo nayiphi na inkqubo yemichiza, ukucocwa okwaneleyo emva kwenyathelo ngalinye kubalulekile. Iintsalela zetyuwa zinokuthintela. I-rinsing kufuneka ijongwe kwaye ixabiso le-p kufuneka ligcinwe ngezantsi 8.5. Yomisa imilebe nganye nganye kwaye uqiniseke ukuba umphezulu awuzange ungcoliswe yioyile efana neoyile yesandla.
Ukufakwa kunye nokuLinga
I-BORD YOKUQESHWA
1. I-250ºF (100 ° C) ibheke ichibi ukususa umswakama. Gcina imizuzu kwindawo elawulwa ngokuqinileyo kwaye usebenzise kwiiyure ezingama-24.
2. Intsimi yoxinzelelo kufuneka isetyenziswe phakathi kweplate yesixhobo kunye neepleyiti ze-electrolytic ezivumela ukuhambisa uxinzelelo kwiplate yolawulo. Iindawo zoxinzelelo oluphezulu kwiBhodi nakwiBhodi yeSiphaluka eziya kuzaliswa ziya kuthathwa yintsimi. Intsimi ikwahlula iyunifomu evela ngaphandle ukuya kwiziko. Oku kudala ubungqingqwa obufanayo kwiBhodi yoLawulo uye kwiBhodi yeBhodi.
I-3. IBhodi kufuneka iqulathe iingqengqelo ze-TAC ye-TAC ebonelelwe ngumthengisi. Kufuneka kuthathwe ukhathalelo ukuthintela ungcoliseko xa usika iingqengqelo kunye nokubekwa. Kuxhomekeka kuyilo lwesekethe kwaye kugcwalise iimfuno, enye ukuya kuthi ga kwi-Tounds ezintathu ezinobunzima ziyimfuneko. Indawo eza kuzaliswa kunye neemfuno zeDeokric zisetyenziselwa ukubala imfuno ye-0.0015 "(i-38 micron) yephepha. Coca intsimbi yentsimbi okanye i-aluminium ye-aluminium yesipili iyacetyiswa phakathi kwamanzi.
4. Ukuncedisa kulwaliso, i-30 yemizuzu engama-20 isetyenziswa ngaphambi kokufudumeza. I-vacuum igcinwa kuwo wonke umjikelo. Ukukhuphela umoya kuya kunceda ukuqinisekisa ukugqitywa kwe-engertication yesekethi.
5. Ukubek'esweni ubushushu ngebhayisikile efanelekileyo kunokugqitywa ngokubeka i-thermocouples kwindawo yeplate yeziko.
I-6. IBhodi inokulayishwa kwi-Toud okanye i-Prefee ePhezulu iPhepha lokuqalisa. Ukunyuka kwe-thermal kunye nokuhamba ngebhayisikile kuya kwahluka ukuba umhlaba woxinzelelo awusetyenziswanga ukubuyekeza. Igalelo lamafutha kwiphakheji aligxeki, kodwa kufuneka lilawulwe kangangoko linakho ukunciphisa umsantsa phakathi kweendawo eziphakathi kunye neziko. Ngokwesiqhelo, amaxabiso obushushu ukusuka kwi-12 ukuya kwi-20 ° C / i-6- 7 ° C / min) ukuya kwi-425ºF (220 ° C).
7. Xa sele ilayishwe kumatshini wokushicilela, uxinzelelo lunokusetyenziswa kwangoko. Uxinzelelo luya kwahluka ngokobukhulu bephaneli yolawulo. Ifanele ilawulwe kuluhlu lwe-100-200 psi (i-7-14 bar).
8. Gcina ubushushu obushushu obushushu kwi-425ºF (230 ° C) ubuncinci imizuzu eli-15. Iqondo lobushushu akufuneki lidlule kwi-450ºF (235 ° C).
9. Nciphisa ixesha ngaphandle koxinzelelo lwelizwe ngexesha lokutshata (umzekelo, ixesha lokudlulisela ukusuka kucinezelo oshushu kuMatshini oBandayo). Gcina uxinzelelo loxinzelelo lwelizwe de ibe ngaphantsi kwe-200ºF (100 ° C).
