Nhazi Molekụla na Àgwà Anụ Ahụ

SG3 (Ọkwa Mgbanwe Dị Elu)
E ji ogo polymerization nke 1300 - 1500 na uru K - nke 70 - 72 mepụta ya, ọkwa a nwere agbụ molekul dị ogologo nke na-eme ka njide plasticizer dịkwuo mma. Nkesa ya nke 60 - 250 μm na-eme ka mgbasa dị n'otu n'ime usoro ngwakọta dị nro, na-enye ohere ịnweta 25 - 35g nke plasticizer kwa 100g resin. Ọdịdị amorphous a na-enweta na-enye ogologo pụrụ iche mgbe ọ gbasịrị, na-eme ka ọ dị mma maka ngwaahịa chọrọ mgbanwe ugboro ugboro na-enweghị mgbawa.

SG5 (Ọkara dị iche iche - Ọkwa)
N'ịhazi ogo polymerization nke 1000 - 1100 na uru K - nke 65 - 67, SG5 na-enye ala dị n'etiti. Njupụta ihe ndị dị na ya kachasị mma (0.45 - 0.58g/mL) na-eme ka mmiri gbazee nke ọma ma na-akpụzi ihe na-agbaze n'ime mpụta na ntụtụ, ebe nnabata plastikizer dị nro (20 - 28g/100g) na-eme ka mgbanwe site na sheath waya siri ike gaa na profaịlụ mgbanwe dị ala. Usoro nhazi nke yinye molekul na-ebelata ntụpọ nhazi, na-ahụ na ọkpụrụkpụ mgbidi na-adịgide adịgide na mpụta paịpụ.

SG7 (Ọkwa Injinịa siri ike)
Site na ogo polymerization nke 700 - 850 na uru K - nke 60 - 62, SG7 na-ebute ụzọ maka arụmọrụ nkwakọ ngwaahịa molekul maka nkwụsi ike. Ọdịdị obere ya nke 40 - 180μm (njupụta 0.50 - 0.62g/mL) na-ebelata oghere dị n'akụkụ e kpụrụ akpụ, na-eme ka iguzogide mmetụta dịkwuo mma na profaịlụ ụlọ. Mbubata plasticizer dị ala (15 - 22g/100g) na-enye ohere maka usoro siri ike kpamkpam, ebe residual vinyl monomer ≤3μg/g na-emezu ụkpụrụ nchekwa nri maka ngwa nkwakọ ngwaahịa.

Sistemụ Ngwa

SG3: Ọkachamara Ngbanwe Mgbanwe
N'ọrụ ugbo, ihe nkiri SG3 nke nwere ihe mgbakwunye plastik 40 - 50 phr na-emepụta mkpuchi ụlọ griin haus nke kwụsiri ike na UV, na-edozi nnyefe ìhè na ike iguzogide anya mmiri. Maka ojiji ahụike, obere ọdịnaya monomer ya na-eme ka ọkpọkọ dị nro maka igwe dialysis, ebe ọ na-emepụta ụkwụ na-agbanwe agbanwe nke na-ejigide ọdịdị n'agbanyeghị mgbanwe okpomọkụ.

SG5: Ịnyịnya Ọrụ Ụlọ Ọrụ
Ndị na-emepụta eriri waya na-eji usoro plasticizer SG5 nke 10 - 20 phr emepụta ihe mkpuchi mkpuchi ọkụ na-adịghị ike maka grid ike, na-ejikọta mkpuchi eletriki na ike igwe. N'ọrụ owuwu ya, ọ na-apụta n'ime mpempe mkpuchi na-adịghị emerụ ihu igwe maka windo, ebe ike ya dị ala na-eguzogide mmebi ozone. Ntụtụ - ihe ndị e ji arụ ụgbọ ala, dị ka ihe ndozi ọnụ ụzọ, na-erite uru site na mmetụta ya - ike - na - ibu.

SG7: Onye Mmeri Ike
Sistemụ ọkpọkọ ụlọ ọrụ na-adabere na modulus dị elu nke SG7 maka ọkpọkọ mmiri na-eguzogide kemịkalụ na nrụgide - nke a na-enye ọkwa mmiri. Profaịlụ windo ndị a na-apụta, mgbe ejikọtara ya na titanium dioxide, na-egosipụta agba pụrụ iche n'èzí. Ndị na-emepụta eletrọniki na-eji ya maka ịgba ntụtụ - ebe a na-etinye ngwa eletrọniki, na-eji ya eme ihe maka nkwụsi ike ya n'oge mgbakọ okpomọkụ dị elu.

Nuances Njikwa Okpomọkụ
SG3 chọrọ njikwa okpomọkụ siri ike (160 - 180°C) iji gbochie ire ere tupu oge eruo; ọbụna oke okpomọkụ 10°C nwere ike ibute ntọhapụ hydrochloric acid, na-eduga na odo odo. N'ụzọ dị iche, SG7 na-anabata nhazi 180 - 200°C, na-enye ohere ka ọnụego mmịpụta ngwa ngwa maka nnukwu paịpụ dayameta, ọ bụ ezie na ịgafe 210°C nwere ike ibute mkpochapụ yinye molekul.

Nhazi Sistemụ Mgbakwunye
Nkwụsi ike: SG3 chọrọ 1 - 2 phr nke calcium - zinc composite stabilizers iji lụso mbibi okpomọkụ ọgụ n'oge nhazi plastik dị elu, ebe SG7 chọrọ naanị 0.5 - 1 phr n'ihi obere nrụgide nke plasticizer kpatara.
Mmanya: Akara niile na-erite uru site na 0.2 - 0.5 phr nke wax polyethylene, mana SG3 nwere ike ịchọ ka e jiri ya mee ihe karịa iji belata esemokwu dị n'ime ihe ndị dị nro.
Ihe Mgbakwunye Ọrụ: Ọgwụ antioxidant dị na usoro SG7 na-agbatị ndụ ọrụ n'èzí, ebe ihe ndị na-agbanwe mmetụta na SG5 na-eme ka iguzogide oyi na ihu igwe dịkwuo mma.

Ọkachamara Injinia na Nhazi Resin
