Goobtii wax soo saarka ee wax soo saarka, xaashiyaha ka-hortagga pom-ka ee loo yaqaan 'pom-ka' pom pom 'ee loo yaqaan' Eleptrict 'ee qalabka elektiroonigga ah, ayaa gacanta ku haya xaaladaha qalabka semiconductor iyo xaalado kale oo ay ugu wacan tahay xaaladaha wanaagsan, xidho xasilloonida caabbinta iyo xasilloonida caabbinta. Si kastaba ha noqotee, halista culeyska fekerka ee ay keentay astaamaha sheyga inta lagu gudajiro howsha ayaa inta badan ka dhigeysa injineerrada inay la kulmaan caqabado sida dildilaaca iyo jabinta. Maqaalkani wuxuu isku daraa dhaqammada warshadaha si loo falanqeeyo dhibcaha kor u qaadista iyo istiraatiijiyadaha ka hortagga qaadista ee nidaamka howsha oo dhan.
1. Tilmaamaha tikniyoolajiyadda: Xakamaynta saxda ah si loo siidaayo suurtagalnimada aaladda
Maareynta heerkulka: xakamaynta heerkulka dahabiga ah
Heerkulka ka shaqeynta ee pom-ka-quseeya ee ka hortagga pom waa in si adag loo xakameeyaa 190-215 ℃ (xasaasiyadda xasaasiga ah) ama 165-180 ℃ (fasalka Copolymymer). Ka-badnaan 220 ℃ waxay u nugul tahay jahwareerka iyo siideynta gaaska Dembiyada. Waxaa lagu talinayaa in la isticmaalo tikniyoolajiyadda xakamaynta ee heerkulka ee heerka heerkulka ah:
Placet Marxaladda: PREHET PLATE illaa 80 ℃ ka hor intaadan yareyn si aad u dhinto isku-darka culeyska kuleylka;
Qiyaasta yareynta
Qalabka iyo socodsiinta dariiqa
U adeegso aaladaha 'super-adag'
Marka laga hadlayo isbadallada adag, isticmaal isku darka "Feed Fund + Cady + Cadhada internetka" si loo yareeyo saameynta qalabka.
Qaabeynta qaabeynta qaabdhismeedka
R0.3-r0.5 Firfircoonaanta Kala-guurka ayaa qasab ku ah geesaha si ay u tirtiraan feejignaanta walaaca xagal-midig;
Qeybo kala duwan oo dhumuc weyn leh ayaa u baahan in lagu qalabeeyo dib-u-xoojinta feeraha, iyo saamiga ugu ballaadhida dhumucda lagula talinayo in la noqdo ≤1: 1.5.
Midda labaad, furaha ka hortagga dillaac: nidaamka kahortaga naqshadeynta loo maro ka dib
Wax ka badalida maaddada iyo xakamaynta buuxinta
Cadadka buuxinta dawada ka hortaga (sida fiberka kaarboon iyo kaarboon nanotubes) lagu daray waa in lagu xakameeyaa 15%. Dheeri badan oo xad dhaaf ah ayaa horseedi doonta hoos udhaca xoogga isku-darka ee is-dhexgalka. Waxaa lagu talinayaa in la isticmaalo qaab-dhismeedka Qaab-dhismeedka Core-Shell ee wax ka badalida tikniyoolajiyadda si loo wanaajiyo kala-guurka buuxinta.
Habka loo sii daayo walaaca
Daaweynta daaweynta ayaa la sameeyaa isla markiiba ka dib markii la farsameeyo: 140 ℃ Heerkul joogto ah muddo 2 saacadood ah, oo si tartiib ah ayuu u qaboojiyaa heerkulka qolka;
Kanaalka biyo qaboojinta ee gariirka ah ayaa lagu dhajiyaa naqshadda caaryada si loo sameeyo heerka qaboojinta sheyga ≤2 ℃ / min.
Kor u qaadista dhaqanka deegaanka
Kaydinta wax soo saarka ee dhammeysatay waxay u baahan tahay in la ilaaliyo huurka xamuulka ee 40-60% Rh iyo heerkul ah 20-25 ℃ si looga fogaado inaad la xiriireyso agabyada Polar sida PVC;
Acetone waa mamnuuc in lagu nadiifiyo dusha sare, waxaana lagu talinayaa in lagu tirtiro xalka aalkolada ISOPOPOPL (IPA) ee ≤70%.
III. Dhiirrigelinta ka socota kiisaska arjiga warshadaha
Markii la sameeyo taarikada Tooska ah ee loo yaqaan 'anti-status pom', soo-saare qalab semiconduactor ah ayaa hoos u dhigay heerka jabsiga laga bilaabo 8% ilaa 0.5% iyada oo loo marayo horumarka soo socda:
Iridda caqabadaha waxaa loo beddelay naqshad wanaagsan oo maraq qaab leh, oo ballaadhkii iriddeediina waxaa kordhay 1.2 jeer dhumucdii derbiga;
Cadaadiska duritaanka waxaa lagu xakameeyay seddex marxaladood: bilowga 80mpa → bartamihii 60mpa → Haysashada cadaadiska 40mpa;
Waxay soo bandhigtay nidaam korjoogteyn khadka tooska ah si loo xakameeyo heerkulka caaryada ee isbeddelka heerkulka waqtiga dhabta ah (± 1 ℃ sax ahaanta).
Gunaanad: Nidaam-soo-saaridda Nidaamka ayaa hogaamisa sii deynta qiimaha maaddada
Tayada wax ka qabashada ee xaashiyaha ka soo horjeeda ee ka soo horjeedka pom-ka ee anti-static-ka ah kuma tiirsana guryaha waxyaabaha, laakiin sidoo kale waxay u baahan tahay isku dubbarid silsilado buuxa oo ka socota naqshada thermuundynamic-ka ah ee loo yaqaan 'thermuundyamic' ee loo adeegsado xakamaynta deegaanka. Iyada oo ay weheliso horumarka tikniyoolajiyadda wax ka badalida (sida adeegsiga wakiilada ka hortagga dawooyinka ka hortaga ee nano), arjiga figradaha ka hortaga dawooyinka), ee rajooyinka laga qabo ee maaddadan ee aqalkan dhamaadka-dhamaadka sida 5G saldhigyada saldhigyada iyo aaladda caafimaadku waxay noqon doonaan ballaadhan mustaqbalka.
Shirkaddeenu waxay si qoto dheer ugu mashquulsan tahay balaastigga injineerinka waxqabadka sare, waxaana ka go'an inay siiso xalka maaddada hal-abuurka ah ee warshadaha soo-saarka ee ugu sareeya. Alaabooyinkayaga ugu muhiimsan waxaa ka mid ah go'yaal caag ah oo dhameystiran sida poloyoxymymerene (pom), polycharbonate (polychertonenenene (polyphertones), iwm), polyphertones (polythertone), phenole-ka (phenethertone) iyo gudiga galaaska galaaska ephox. Iyada oo leh guryo aad u wanaagsan sida caabbinta heerkulka sare, iska caabbinta, iyo xoog sare, alaabooyinkeena ayaa si weyn loogu adeegsadaa gawaarida tamarta cusub, mashiinka elektaroonigga ah, mashiinnada warshadaha, aerospace iyo beero kale.
