Qaab-dhismeedka Halo-ka-hortagga Ololka ee Halogen-ka ah ee Nidaamka Dahaarka TPU iyadoo la adeegsanayo Dareeraha DMF

Nidaamyada dahaarka TPU ee isticmaalaya Dimethyl Formamide (DMF) oo ah dareeraha, isticmaalka aluminium hypophosphite (AHP) iyo zinc borate (ZB) oo ah kuwa dabka celiya waxay u baahan tahay qiimeyn nidaamsan. Hoos waxaa ku qoran qorshe falanqayn iyo hirgelin oo faahfaahsan:

I. Falanqaynta Suurtagalnimada ee Aluminium Hypophosphite (AHP)

1. Habka iyo Faa'iidooyinka Ka-hortagga Ololka

• Habka:
• Waxay ku burburtaa heerkul sare si ay u soo saarto asiidhyada fosfooriga iyo metaphosphoric, taasoo kor u qaadaysa sameynta char ee TPU (dib u dhigista ololka wejiga isku dhafan).
• Waxay sii deysaa xagjirrada PO· si ay u joojiso falcelinta silsiladda gubashada (dib u dhigista ololka marxaladda gaaska).
• Faa'iidooyinka:
• Halogen la'aan, qiiq yar, sunta yar, oo u hoggaansan RoHS/REACH.
• Xasillooni kuleyl oo wanaagsan (heerkulka kala-baxa ≈300°C), oo ku habboon hababka qalajinta TPU (badanaa <150°C).

2. Caqabadaha Codsiga iyo Xalalka

3. Qaabaynta iyo Habka lagu taliyay

• Tusaalaha Qaacidada:
• Saldhigga TPU/DMF: 100 ph
• AHP-ga dusha sare wax laga beddelay: 20 hr
• Zinc borate (ZB): 5 phr (isku-darka xakamaynta qiiqa)
• Kala-bixiyaha (BYK-110): 1.5 hr
• Qodobbada Muhiimka ah ee Habka:
• Isku qas AHP oo leh kala firdhiye iyo qayb ka mid ah DMF marka aad xiirto (≥3000 rpm, 30 daqiiqo), ka dibna ku qas dareeraha TPU.
• Qallajinta dahaarka kadib: 120-150°C, waqtiga ku kordhi 10% si loo hubiyo uumi-baxa DMF oo dhammaystiran.

II. Falanqaynta Suurtagalnimada ee Zinc Borate (ZB)

1. Habka iyo Faa'iidooyinka Ka-hortagga Ololka

• Habka:
• Waxay samaysaa lakab galaas ah oo B₂O₃ ah heerkul sare, iyadoo xannibaysa ogsijiinta iyo kulaylka (daciifnimada dabka ee wejiga isku dhafan).
• Waxay sii deysaa biyaha xiran (~13%), waxay qastaa gaasaska ololaya waxayna qaboojisaa nidaamka.
• Faa'iidooyinka:
• Saamayn xooggan oo isku-dhafan oo leh AHP ama aluminium trihydroxide (ATH).
• Xakamaynta qiiqa oo aad u fiican, oo ku habboon isticmaalka qiiqa yar.

2. Caqabadaha Codsiga iyo Xalalka

3. Qaabaynta iyo Habka lagu taliyay

• Tusaalaha Qaacidada:
• Saldhigga TPU/DMF: 100 ph
• Cabbirka Nano-ga ZB: 8 phr
• AHP: 15 saacadood
• Wakiilka qoynta (Tego 750W): 1 phr
• Qodobbada Muhiimka ah ee Habka:
• Ku faafi ZB DMF kahor intaadan ku darin wax lagu shiido ul (cabirka walxaha ≤2μm) ka hor inta aadan ku qasin dareeraha TPU.
• Kordhi wakhtiga qalajinta (tusaale ahaan, 30 daqiiqo) si looga fogaado qoyaanka haray ee saameeya dib u dhaca ololka.

III. Qiimaynta Wadajirka ah ee Nidaamka AHP + ZB

1. Saamaynta Isku-dhafka ah ee Ka-hortagga Ololka

• Isku-dhafka Gaaska iyo Wejiga Isku-dhafan:
• AHP waxay bixisaa fosfooraska loogu talagalay dab-shidka, halka ZB ay xasiliso lakabka dab-shidka oo ay xakameyso iftiinka dambe.
• LOI isku dhafan: 28-30%, UL94 V-0 (1.6mm) waa la gaari karaa.
• Xakamaynta Qiiqa:
• ZB waxay hoos u dhigtaa qiiqa qiiqa >50% (tijaabada Kalorimeter-ka Cone).

2. Talooyinka Isu-dheellitirka Waxqabadka

• Magdhawga Hantida Farsamada:
• Ku dar 2-3% TPU plasticizer (tusaale ahaan, polycaprolactone polyol) si aad u ilaaliso dabacsanaanta (kordhinta > 300%).
• Isticmaal budada ultrafine (AHP/ZB <2μm) si aad u yareyso luminta xoogga riixitaanka.
• Xakamaynta Xasilloonida Habka:
• Ku hay isku-dhafnaan dheecaan ah 2000-4000 cP (Brookfield RV, spindle 4, 20 rpm) si aad u hesho dahaadh isku mid ah.

IV. Isbarbardhigga Waxyaabaha Dareeraha Ku Salaysan Dareeraha

V. Tallaabooyinka Hirgelinta ee lagu taliyay

1. Tijaabada Miisaanka Shaybaarka:

• Qiimee AHP/ZB si gaar ah iyo si isku dhafan (rarista jaantuska: 10%, 15%, 20%).
• Qiimee xasilloonida kala firdhinta (ma jiraan wax ka soo baxaya fadhiisin 24 saacadood ka dib), isbeddellada viscosity-ga, iyo isku-midnimada dahaarka.

1. Xaqiijinta Miisaanka Tijaabada ah:

• Hagaaji xaaladaha qalajinta (waqtiga/heerkulka) oo tijaabi dib u dhigista ololka (UL94, LOI) iyo sifooyinka farsamada.
• Isbarbardhig kharashyada: Haddii AHP+ZB ay kharashyada hoos u dhigto >30% marka loo eego FR-yada dareeraha ah, waa mid dhaqaale ahaan waxtar leh.

1. Diyaarinta Kor-u-qaadista:

• La shaqee alaab-qeybiyeyaasha si aad u horumariso batches-yada AHP/ZB ee hore loo kala firdhiyey (ku salaysan DMF) si loo fududeeyo wax soo saarka.

VI. Gunaanad

Iyada oo la adeegsanayo hababka kala firdhinta ee la xakameeyey, AHP iyo ZB waxay u adeegi karaan sidii wax ku ool ah oo ka hortagga ololka dahaarka TPU/DMF, iyadoo la bixinayo:

1. Wax ka beddelka dusha sare + kala-soocidda xiirashada sarewaxaa loo adeegsadaa si looga hortago isku-ururinta walxaha.
2. AHP (aasaaska koowaad) + ZB (isku-dhafka)waxay dheellitirtaa hufnaanta iyo kharashka.
3. Waayo,hufnaan/dabacsanaan sareShuruudaha, FR-yada dareeraha ah ee fosfooraska-nitrogen-ka (tusaale ahaan, Levagard 4090N) ayaa weli la doorbidaa.
