Tilmaamaha Alaabta
1.Waa maxay maadada PC?
PC: polycarbonate, waxaa iska leh qalabka thermoplastic. Qalabkani waa hufnaan, wax yar huruud ah, ma fududa in la beddelo midabka, qallafsanaanta iyo adkaanta iyo awoodda saameyntu si gaar ah ayey u weyn tahay, in ka badan 10 jeer taas oo ah CR 39, oo ah heerka ugu sarreeya ee qalabka thermoplastic .Degganaanshiyo wanaagsan oo kulaylka, shucaaca kulaylka, hawada iyo ozone.Waxay nuugi kartaa dhammaan fallaadhaha ultraviolet ee ka hooseeya 385nm, taasoo ka dhigaysa muraayad ammaan ah.Marka lagu daro iska caabbinta kulaylka sare, caabbinta saliidda, dufan iyo aashitada, nuugista biyaha hooseeya, xasilloonida cabbirka sare, waa nooc ka mid ah walxaha ilaalinta deegaanka oo la isticmaali karo marar aan la tirin karin.Khasaarooyinku waa walbahaar weyn, fududahay in la dilo, si xun u liidata oo leh resins kale, iskudhaf sarreeya oo sarreeya, aan lahayn saliidayn iskeed ah.
2. Astaamaha ugu muhiimsan ee lenska PC:
①miisaan fudud
Muraayadaha kombuyuutarku waxay leeyihiin cuf-jiid gaar ah oo ah 1.2, halka muraayadaha CR-39 ay leeyihiin cuf-jiid gaar ah oo ah 1.32, index refractive 1.56 waxay leedahay cuf-jiid gaar ah oo ah 1.28, muraayadduna waxay leedahay cufis gaar ah oo ah 2.61.Sida iska cad, oo ka mid ah qeexitaannada isku midka ah iyo cabbirka joomatari ee muraayadda, muraayadaha PC, sababtoo ah saamiga ugu yar, waxay sii yareeyaan miisaanka muraayadaha.
② muraayad khafiif ah
Tusaha dib-u-celinta PC waa 1.591, CR-39 (ADC) index refractive waa 1.499, index refractive index waa 1.553.Marka uu sareeyo index refractive waa, dhuuban muraayadaha, iyo lidkeeda.Marka la barbar dhigo muraayadaha CR39 iyo muraayadaha resinka kale, cidhifka muraayadaha indhaha ee PC myopia waa kuwo khafiif ah.
③Amaan aad u wanaagsan
Muraayadaha kombuyuutarku waxay leeyihiin iska caabin aad u wanaagsan, oo loo yaqaan "boqorka caagga ah", waxaa si ballaaran loogu isticmaali karaa soo saarista daaqadaha duulista, muraayadaha rasaasta, maaskarada rabshadaha iyo gaashaanka.Awoodda saamaynta kombuyuutarku waa ilaa 87/kg/cm2, taas oo ka badan tan zinc iyo aluminiumka la tuuray waana 12 jeer ka CR-39.Muraayadaha uu sameeyay PC-gu waxa lagu dhejiyaa dhulka sibidhka si ay u dul istaagaan oo aanay jabin, waana muraayadaha kaliya ee “aan jabin”.Ilaa hadda, muraayadaha kombuyuutarku waa kuwa labaad marka la eego badbaadada.
Nuugista shucaaca ultraviolet
Daawooyinka casriga ah ayaa xaqiijiyay in iftiinka ultraviolet uu yahay sababta ugu weyn ee caadka indhaha.Sidaa darteed, shuruudaha nuugista iftiinka ultraviolet ee muraayadaha ayaa aad iyo aad u cad.Marka loo eego muraayadaha muraayadaha indhaha ee guud, maaddada lafteedu waxay sidoo kale leedahay qayb ka mid ah waxqabadka nuugista iftiinka ultraviolet, laakiin haddii aad rabto inaad si wax ku ool ah uga hortagto iftiinka ultraviolet, waa inaad ku dartaa qadar gaar ah oo nuuga iftiinka ultraviolet halka muraayadaha PC myopia ay 100% xannibi karaan ultraviolet iftiin.
⑤ iska caabin cimilada wanaagsan
PC waa mid ka mid ah balaastikada injineernimada leh ee iska caabbinta cimilada aad u fiican.Marka loo eego xogta tijaabada ah ee gabowga dabiiciga ah ee dibadda, xoogga jilicsanaanta, cirridka iyo tilmaamayaasha etiolation ee PC wax badan kama beddelin ka dib markii la dhigay bannaanka 3 sano.
3. Waa maxay faraqa u dhexeeya HC, HMC iyo SHC?
| Dahaarka adag | Daahan AR / Daahan badan oo adag | daahan Super hydrophobic |
| waxay ka dhigtaa muraayadda aan dahaadhka ahayn mid adag oo kordhisa iska caabbinta nabarrada | waxay kordhisaa gudbinta muraayadda waxayna yaraynaysaa milicsiga dusha sare | muraayada waxay ka dhigtaa mid aan biyuhu ahayn, antistatic, silbasho lid ku ah iyo caabbinta saliidda |
