E pa ana ki te waahanga i hangaia o te muka karaihe he nui te kiko o te boron, kia ahei ai te whakahaere i te reo ki raro.

10. Dicyandiamide (Raukahuri)

He momo whakapakeke epoxy resinima hei whakapakeke i te kaihoko piripiri, na te mea he ngatahi te rāpoi ngota me te amine tuatahi (-NH2), amine tuarua (= NH), me te amine tuatoru (≡NH) e toru te kaha o te tauhohenga kaha kaha, he uaua tino uaua , e mohiotia ana ko Cyano-guanidine cyanide Guanidine. Engari na te kaha o te mimiti o te wai ki nga taonga, he raru kei roto i te pereti ki te kohikohi i te “recrystallization”, no reira me tino pai te whenua kia uru ki roto i te kapia rumaki.

11, Calorimetry Matawai rerekee (DSC) moroiti Matawai i te kaari wera

Ma te ngawari, ka wera ana te taonga, ka rere ke te tere o te “wera” e rere ana ki te taonga (MCAL / SEC) i nga rereketanga o te mahana. Ma te DSC te mehua i tenei “tere tere wera” (te rereketanga ranei o te rereketanga o te wera) i nga rereketanga o te mahana. Hei tauira ka wera ana te miihini epoxy arumoni, ko te tere rererangi o te wera i nga rereketanga rerekee me te rerekee, engari e tata ana ki te “huringa huringa karaihe, te tere o te wera i waenga i ia ℃ ka kitea he rereketanga nui, te kokiri o te huri tohu e rite ana ki te paemahana o te whakawhitinga whakawhiti, ara ko te Tg mo te kapia, na te Tg DSC ki te whakatau e waatea ana. Ko te huarahi DSC ko te tauira (S) me te tohutoro (R) i te wa ano e whakawera ana, na te mea e rua nga “wera wera” he rereke, no reira he rereke te mahana, engari ko te waahi i waenga i te △ T ka taea te pupuri kaore i whakarereke. Heoi, ka tata ana ki te Tg, △ T i waenga i a ratau ka tino rereke, ka taea e DSC te ine i te rereketanga o te rereketanga o te mahana. He “whakarereke rereketanga wera” (DTA) kua whakarereketia. Hei taapiri ki te WHAKATAKI o te polymer Tg, ka taea hoki te whakamahi i te DSC ki te mehua i te wera motuhake o te kirihou, te kirikiri, te hononga ki te hononga, me te ma, he mea nui te “wetewete waiariki” taputapu.

12. Tuku CoaTIng

He huarahi maamaa me te kore utu hei whakakakahu (ko te matotoru o te kiriata hiako e pa ana ki te viscosity me te tere o te koti). Ko te prepreg (kohinga rauemi poari taiawhio) e whakamahia ana i tenei wa. Ka taea te pani i waho, a ka uru ano ki te waahi o te muka karaihe karaihe (no reira ka mohiotia ano he taonga kua wairangi).

Karaihe hiko hiko E-karaihe

Ko te E-karaihe na OWens-Corning Fiberglass Co. As a result of the circuit board industry has been used for a long time, it has become an academic noun. Hei taapiri ki te silicon taketake me te konupūmā, he iti noa te pāhare pāporo me te konutai, engari he maha te boron me te konumohe. He pai tona kiriweti me te whakahaere, kua whakamahia whānuitia i roto i nga kaupapa whakapakari tira poari taiawhio.

I roto i te umanga poari taiawhio, ko te kohi nui rawa atu o te miihini me te kara o te hononga, me te karaihe muka karaihe, kara whariki karaihe, me te papa hiato pepa kraft ma, a ka taea te whakauru i nga momo taapiringa katoa, kia tutuki ai te kaupapa o te koretake. me te mahi nui, hei papanga turanga mo nga taumata katoa o te papa taiawhio.

15. Exotherm (ānau)

I te wa o te polymerization me te whakapakeke o nga momo rerenga, ko te kupu mo te aukati o te tuku wera i te wa kua roa. Ko te wa e tukuna ana te wera nui ko te tohu teitei o te nekehanga pāmahana. Ana ko te Exothermic Reaction- he Urutanga matū Exothermic.

16. Kakano

E pa ana ki te waahanga nui o nga momo papanga, ko te tikanga he kotahi te miro i whiria hei whenu kotahi, he miro miro-maha ranei, ka whiria ki roto i te papanga e hiahiatia ana e te “warp” me te “weft”. Ko te Kakano e pa ana ki te Huri Kakano, i te Kaki Tuturu ranei.

17. Fill in weft direction

Ko te Kakarama miihini miihini taarua ranei, ko te ahunga o te pungarehu he iti ake i te maha o te pauna ia waahanga roa, na reira ka iti ake te kaha. He taurite taurite tenei kupu.

18, Taha Ahi

E pa ana ki te poari iahiko kei roto i te miihini pereti miihini, kia tutuki ai te taumata o te mura o te mura o te ahi (i te UL94 HB, VO, V1 me te taumata V2 4), me taapiri etahi matū me aata whaiwhakaaro ki roto i te tauira resin, penei i te bromine, silica, alumina, peera i te FR – 4, neke atu i te 20% o te bromide), ka taea e te papa o te mahi te whakatutuki i etahi aukati mura. Ko te tikanga FR-4 ahi-aukati ka tohua ki te tohu a te kaihanga UL “tohu whero” i runga i te Warp o tana tihi (papanga rua) hei tohu he ahi-aukati. Ko te G-10 kaore he mura o te ahi ka taea te taarua me te “karaariki” tohuwai ki te ahunga warp. He taurite ki te Flame Retardent, engari ko te kupu tika mo te poari ara iahiko ko te Fire Resist, kaore nei e kawenga, kaore hoki e tika kia whakaatuhia e nga reimana.

19, Gel Time

E pa ana ki te maihao rakau i te atamira b. Whai muri i te whakaweratanga o te wera o-waho, ka huri te maihao o te rakau mai i te totoka ki te wai, katahi ka aataima ana ka pakari ano. I te wa e whakahaerehia ana, ko te “maha o nga hēkona” katoa e pa ana ki te ngohengohe “kia kitea he colloidality” e kiia ana ko “te wa colloidization”. Arā, i te mahinga o te pereti maha-papanga e peehi ana, ka taea e te kapi rerenga te pei i te hau ka whakakiihia nga piki me nga heke o te raina o roto. Ko te maha o nga hēkona ka taea te whakamahi ko te hiranga whaihua o te wa whakapiri. He waahanga nui tenei mo te kiriata-haurua-whakaata i te prepreg.
